What are the AT&T (att.net) IMAP settings?

Use imap.mail.att.net on port 993 with SSL. Sign in with your full email address on any AT&T domain and a secure mail key, not your regular password.

Why does my email app keep rejecting my correct password?

AT&T blocks regular passwords in email apps without OAuth sign in. Create a 16 character secure mail key at att.com/myatt under Profile and Sign-in info and use it as the password.

Should I pick POP3 or IMAP?

IMAP for almost everyone. It keeps your phone, computer and webmail in sync. POP3 fits only a single computer setup and on AT&T it uses different servers: inbound.att.net and outbound.att.net.

Are sbcglobal.net and bellsouth.net settings the same as att.net?

Yes, identical. All 12 AT&T family domains including sbcglobal.net, bellsouth.net, pacbell.net and currently.com use the same servers, ports and secure mail key system. Only the username changes.

I lost my secure mail key. Can I see it again?

No. Secure mail keys show only once. Create a new one at att.com/myatt under Profile and Sign-in info. The old key keeps working until you delete it.

Is it safe to put my AT&T account in Outlook or Apple Mail?

Yes, when you use a secure mail key or OAuth sign in. A key only grants mailbox access and can be deleted individually at any time without changing your real password.

My AT&T email worked for years and suddenly stopped. Why?

AT&T requires a secure mail key for every app without OAuth sign in and it deletes existing keys whenever it locks an account. Either way, the fix is creating a fresh secure mail key.

How do I move my AT&T emails to another account?

Use an email migration tool that copies mail between accounts over IMAP. Enter the AT&T IMAP settings with a secure mail key for the source and your new provider's details for the destination.

AT&T Email Settings: IMAP, SMTP, POP3 and Secure Mail Key

Q: Why is my AT&T email not working today?

Sign in at currently.com first. If webmail works, the problem is your app and almost always the secure mail key. If webmail fails too, the account is locked or AT&T has a service issue. Clearing a lock deletes your keys, so create a fresh one after.

Quick answer: the AT&T IMAP server is imap.mail.att.net, port 993, SSL. SMTP is smtp.mail.att.net, port 465 (587 also works in most apps). POP3 is inbound.att.net, port 995, sending through outbound.att.net. Use your full email address and a secure mail key. All 12 AT&T domains, including sbcglobal.net and bellsouth.net, use these settings.

Every setting on this page is verified with live IMAP and SMTP connections from Univik email software. We build email backup and converter tools since 2013, so we test against these servers every day. See what changed →

What Changed Recently#

AT&T changes login rules more often than server addresses. Here is the current status and what it means for your setup.

Latest update

AT&T confirmed it deletes secure mail keys when an account gets locked or blocked. If your email app suddenly fails after a security lock, your old key is gone. Create a new one and update every device. Keys otherwise never expire and survive normal password changes.

The Gmail change

Gmail stopped pulling AT&T mail into Gmail inboxes. Google removed the "Check mail from other accounts" POP feature from Gmail on the web. If your AT&T mail used to appear inside Gmail and quietly went silent, this is why. It's not an AT&T problem. Mail already imported stays in Gmail. To keep reading AT&T mail going forward, connect an email app with the IMAP settings below or move the mailbox to the account you actually use.

Our documentation recheck

AT&T refreshed its official POP3 and IMAP settings documentation. No values changed. Servers, ports and the secure mail key requirement all stayed the same, which we confirmed against the updated articles.

The webmail rebrand

AT&T Mail webmail became "Currently, from AT&T". You now read webmail at currently.com instead of att.net. Your address and the servers on this page did not change and new @currently.com addresses joined the same family.

Standing rule

Every email app needs OAuth or a secure mail key. AT&T documents this as the only 2 ways an app can access AT&T Mail. Any app without AT&T OAuth sign in must use a 16 character secure mail key instead of the account password. Still the top reason AT&T setups fail.

Current status: secure mail keys work for IMAP, POP3 and SMTP in any email app. OAuth compatible apps can keep using your regular AT&T password. No deprecation is announced for either method.

Before You Begin#

Get these 2 things right first. If you skip them, your email app will reject the connection even when every server value is correct.

1. Create a secure mail key

Unless your app offers an AT&T or Yahoo sign in window (OAuth), your regular password won't work. You need a 16 character secure mail key as the password.

Where: Secure mail key steps below →

2. Match your outgoing server to your protocol

AT&T uses different outgoing servers: IMAP setups send through smtp.mail.att.net, POP3 setups send through outbound.att.net. Mixing the pairs is the classic "receives but cannot send" mistake.

Where: SMTP settings below →

About AT&T Mail#

AT&T Mail is the email service attached to AT&T internet and phone accounts, branded "Currently, from AT&T" since 2021 and run on Yahoo mail infrastructure.

The service collects addresses from decades of telecom mergers. SBC, BellSouth, Pacific Bell, Ameritech, Prodigy and other regional brands all folded into AT&T and their email domains came along. That is why a @sbcglobal.net or @bellsouth.net address signs in through AT&T and uses att.net servers. The 1 thing that makes AT&T setup different: older email apps must use a secure mail key instead of the account password. AT&T enforces this for every app without OAuth sign in.

Same settings for every AT&T domain: addresses ending in @att.net, @sbcglobal.net, @bellsouth.net, @currently.com, @ameritech.net, @pacbell.net, @swbell.net, @flash.net, @prodigy.net, @snet.net, @nvbell.net and @wans.net all use the identical servers on this page. Your domain only changes the username, never the servers.

Service Name	AT&T Mail (Currently, from AT&T)
Owned By	AT&T Inc.
Mail Platform	Yahoo infrastructure
Webmail Rebrand	currently.com
Email Domains	`@att.net`, `@sbcglobal.net`, `@bellsouth.net`, `@currently.com` and 8 more legacy domains
Webmail URL	currently.com
Protocols Supported	IMAP, POP3, SMTP
Password for Email Apps	Secure mail key (16 characters) or OAuth sign in

AT&T Webmail Login#

You can always read your mail in a browser, whichever AT&T domain your address uses. The official pages are:

Webmail

currently.com

Account and Mail Key

att.com/myatt → Profile

Password Recovery

att.com/support → Forgot password

Watch out for fake support pages. Many pages ranking for AT&T email settings show a phone number and ask you to call for "expert setup help". Server settings are free and public. AT&T never charges to hand them out and Univik never asks you to call anyone. Everything you need is on this page.

AT&T IMAP Settings#

IMAP is the incoming protocol most people should use. It keeps your mail on the server so every device shows the same inbox.

IMAP Server	`imap.mail.att.net`
Port	`993`
Encryption	SSL/TLS (required)
Username	Your full email address including the domain, whether `@att.net`, `@sbcglobal.net`, `@bellsouth.net` or another AT&T domain
Password	Secure mail key
Authentication	Required

AT&T POP3 Settings#

POP3 downloads mail to 1 device. Pick it only if you want a local copy on a single computer. Not sure? See the comparison below. Note the different servers: AT&T POP3 uses inbound.att.net, not the IMAP server.

POP3 Server	`inbound.att.net`
Port	`995`
Encryption	SSL (required)
Outgoing Pair	`outbound.att.net` port `465` SSL (POP3 setups only)
Username	Your full AT&T email address, any domain
Password	Secure mail key

Careful with POP3 delete settings. Some clients remove mail from the server after download. Check "leave a copy on the server" if you still want mail in webmail.

AT&T SMTP Settings#

SSL only: AT&T accepts encrypted connections only. The old unencrypted ports 143 (IMAP) and 110 (POP3) never connect. If your app filled one of them in automatically, correct the port and turn SSL on.

AT&T pairs the outgoing server to your incoming protocol. Each column stays together.

SMTP handles outgoing mail. If you can read mail but not send it, the problem is here. These values pair with IMAP. POP3 setups send through outbound.att.net instead, as shown above.

SMTP Server	`smtp.mail.att.net`
Port (SSL)	`465`, the port AT&T documents officially
Alternate Port	`587` with STARTTLS connects in most clients, though AT&T's own documentation lists 465
Encryption	SSL or STARTTLS (required)
Username	Your full email address
Password	Same as incoming mail
Authentication	Required. Check "My outgoing server requires authentication" in Outlook.

Check AT&T IMAP Settings Online#

You don't need to download anything to check AT&T IMAP settings online. This page is the lookup: every value is verified, current and copyable straight from your browser. Not sure your address belongs to the AT&T family? Type it below and find out instantly.

Does my email address use these settings?

Runs in your browser only. Your address is never sent anywhere or stored.

Want to verify the account itself before configuring an app? Two online checks settle it: sign in at currently.com, which confirms your address and password work, then confirm a secure mail key exists in your myAT&T profile. If both pass, any email app connects with the tables above.

Look Up IMAP Settings for Any Email Domain#

This page covers the AT&T family. For every other address, work email on a company domain included, we run a free online lookup database: imapsettings.com.

imapsettings.com

Check IMAP settings online →

Enter any email address and get the incoming and outgoing server settings for that domain in 1 step:

Incoming server: hostname, port, SSL/TLS and username format

Outgoing server: SMTP hostname, port and encryption

Your address is used only to find the settings for that domain. Nothing is stored or shared.

AT&T Secure Mail Key Setup#

The most common AT&T setup failure is using the wrong password. A secure mail key is AT&T's name for an app password: a 16 character code that replaces your real password inside email apps. Here is which one works where:

The 10 second check that prevents most AT&T setup failures.

Where you sign in	Regular password	Secure mail key
currently.com webmail and myAT&T	✓ Works	✗ Not needed
Outlook, Thunderbird, phone apps (manual IMAP or POP3)	✗ Rejected	✓ Required
Apps with an AT&T or Yahoo sign in window (OAuth)	✓ Works	Not needed

How to Create a Secure Mail Key

Sign in at att.com/myatt and go to Profile → Sign-in info.
Select the email account you want the key for. A dropdown at the top switches between accounts if you have several.
Scroll to Secure mail key and select Manage secure mail key, then Add secure mail key.
Give it a nickname like "Outlook" or "iPhone Mail" and select Create secure mail key.
Copy the 16 character key and paste it as the password in your email app. Create a separate key for each AT&T address and subaccount you set up.

Before you save that key: Secure mail keys never expire and keep working after you change your regular AT&T password. The exception: AT&T deletes all keys when it locks or blocks an account, so a key that "suddenly stopped" usually means you need to create a fresh one.

Set Up AT&T in Email Clients#

The servers and ports are always the same. Only the menus differ. Jump to your app:

Outlook Apple Mail iPhone and iPad Android Thunderbird

Outlook (Windows and Mac)

Open Outlook → File → Add Account (new Outlook: Settings → Accounts → Add account).
Enter your AT&T address, open Advanced options and check "Let me set up my account manually".
Choose IMAP and enter imap.mail.att.net port 993 (SSL) and smtp.mail.att.net port 465 (SSL or 587 if your Outlook version insists on STARTTLS).
Use your secure mail key, not your regular password, when Outlook asks.
Finish and send a test email to yourself to confirm both directions work.

Apple Mail (macOS)

Open Mail → Settings → Accounts → Add Account.
Select AT&T if listed, otherwise choose Other Mail Account.
Enter your name, address and secure mail key, then continue.
If asked for servers, enter the IMAP and SMTP values from the tables above.
Enable Mail in the checkbox list and finish.

iPhone and iPad

Open Settings → Apps → Mail → Mail Accounts → Add Account.
Tap AT&T if listed or tap Other → Add Mail Account.
Enter your details with the secure mail key, then tap Next.
Keep IMAP selected and fill the incoming and outgoing servers if iOS asks.
Tap Save and wait for iOS to verify the account.

Android

Open your mail app (Gmail app, Samsung Email or another) → Add account.
Choose Other (IMAP) when your provider is not in the list.
Enter your address and secure mail key. If auto setup fails, pick Manual setup.
Enter the servers: imap.mail.att.net 993 SSL incoming, smtp.mail.att.net 465 SSL outgoing.
Finish setup and pull down to sync your inbox.

Thunderbird

Open Thunderbird → Account Settings → Account Actions → Add Mail Account.
Enter your name, address and secure mail key, then select Continue.
Thunderbird detects the servers for most providers. Select IMAP if it is not already picked.
If detection fails, choose Configure manually and enter the table values above.
Select Done. Folders sync on first open.

AT&T Webmail Settings#

Server settings connect your apps. These settings control how AT&T mail itself behaves. All of them live at currently.com webmail under the gear icon → More Settings. Bonus: press the ? key anywhere in webmail to see every keyboard shortcut.

Signature

More Settings → Writing email → Signature. Turn it on per account and format your text. Signatures set here appear in webmail only. Outlook and phone apps use their own signature settings.

Vacation Auto Reply

More Settings → Vacation response. Set start and end dates so it turns off by itself. The reply is sent from AT&T servers, so it works even when your computer is off.

Filters and Folders

More Settings → Filters → Add new filters. Rules made here run on AT&T servers, which sort your mail before your phone or Outlook ever sees it. Client side rules only run while that app is open.

Spam and Blocked Senders

More Settings → Security and privacy → Blocked addresses. Add any address to stop its mail. AT&T also filters spam automatically into the Spam folder, which you should check before assuming mail was lost.

POP3 vs IMAP#

Feature	IMAP	POP3
Where mail lives	On AT&T servers (imap.mail.att.net)	Downloaded to 1 device (inbound.att.net)
Multiple devices	✅ Everything stays in sync	❌ Each device sees different mail
Sent and deleted mail	✅ Synced everywhere	⚠️ Stays only on that device
Offline reading	⚠️ Cached mail only	✅ Full local copy
Server storage used	Yes, counts against your quota	Can be freed after download
Best for	Phone + computer, everyday use	Single PC, local archives

Our verdict: pick IMAP unless you have a clear reason not to. If you want a permanent offline archive of your AT&T mailbox, a backup tool does that job better than POP3.

AT&T Sending and Storage Limits#

Hit a limit and AT&T blocks sending temporarily without a clear error. Know the numbers before you bulk forward or migrate a mailbox:

Why IMAP is the right choice for almost everyone with more than 1 device.

Attachment size limit	25 MB per message
Recipients per message	Around 100 (Yahoo infrastructure rule)
Daily sending limit	Not published. Bursts of outgoing mail trigger a temporary send block, usually lifted within 24 hours
Mailbox storage	Not published for legacy accounts. Very full mailboxes slow IMAP sync noticeably
What happens at the limit	Sending fails with a temporary error while receiving keeps working. Wait, then resume at a slower pace

Troubleshooting AT&T Connections#

Find the exact error your email app shows, then apply the fix:

Error you see	What it means	Fix
Password keeps being asked / invalid credentials	App is using your regular AT&T password	Delete the saved password and enter a secure mail key instead. This fixes most AT&T setup failures.
Key worked for months, suddenly rejected	AT&T locked or blocked the account, which deletes all secure mail keys	Sign in at currently.com to clear the lock, then create a fresh key and update every device.
Receives mail but cannot send	Outgoing server doesn't match your protocol	IMAP setups need smtp.mail.att.net, POP3 setups need outbound.att.net. Check "outgoing server requires authentication" too. See SMTP settings.
Cannot connect to server / 0x800CCC0E	Wrong port or encryption	Confirm IMAP 993 SSL or POP3 995 SSL and SMTP 465 SSL. Antivirus and VPN apps can also block these ports.
AT&T mail stopped showing up inside Gmail	Google removed Gmail's "Check mail from other accounts" POP fetching	Nothing on the AT&T side broke and nothing already imported is lost. Connect AT&T directly in an email app with the IMAP settings or use the Univik Email Migration Tool to move everything into your Gmail account for good.
Old mail missing after switching to IMAP	Previous POP3 setup downloaded and removed mail from the server	The mail lives only in the old app's local files. Export it there or use an email converter to move those files into your new setup.

Reader Reported Fixes

Two fixes from real AT&T support cases, for the times the standard steps above come up empty.

Remove the account completely, then add it fresh with the secure mail key. Updating the password in place often fails because Outlook and iPhone Mail keep retrying old cached credentials, which can even trigger an AT&T lock. Deleting the account profile and re adding it with the key as the password from the start connects on the first try.

Sending fails only in an old POP3 profile: switch the outgoing server to outbound.att.net. Profiles created years ago sometimes hold smtp.mail.att.net with a POP3 incoming server. AT&T pairs the servers by protocol, so correcting the outgoing server to the POP3 pair restores sending without rebuilding the account.

Using an SBCGlobal, BellSouth or Other Legacy Address?#

Those brands were regional phone companies that merged into AT&T. Their email domains (sbcglobal.net, bellsouth.net, pacbell.net, ameritech.net, prodigy.net, swbell.net, snet.net, flash.net, nvbell.net, wans.net) all moved onto AT&T infrastructure years ago. There is no separate SBCGlobal or BellSouth mail server anymore. Any guide showing mail.sbcglobal.net or similar old hostnames is out of date.

Setting up any of these addresses? Use every value on this page exactly as written, with your full legacy address as the username and sign in at currently.com for webmail.

Planning to leave the address for good? Back up the mailbox first. Legacy addresses are tied to old AT&T service accounts and access can be lost when the underlying account closes, with no recovery once that happens.

Taking your mail to a new account? The Univik Email Migration Tool copies every folder from the old account to the new one. Enter the IMAP settings from this page for the AT&T side and your new provider's settings for the other. Rather not do it yourself? Our Email Migration Services team plans and runs the whole transfer for you and verifies every folder arrived.

Use These Settings in Univik Email Backup#

The same IMAP settings above let you download your complete AT&T mailbox to your computer. Univik Email Backup saves everything as PST, MBOX, EML or PDF files you keep forever, even if the account closes.

Download Univik Email Backup and install it on Windows.
Select AT&T from the source list. If it isn't listed by name, choose IMAP.
Sign in with your full email address and your secure mail key. Your regular password won't work here either.
If the tool asks for server details, use imap.mail.att.net with port 993 and SSL from the IMAP table above.
Pick a saving format and folder, then start the backup. Large mailboxes download in the background.

Why back up before switching providers: POP3 only grabs the inbox and vacation replies to a closed account bounce. A full IMAP backup keeps every folder, attachment and date stamp in files any email app can open later. Moving to a new account instead of archiving? Use the email migration tool to copy mail directly between accounts.

Email Settings Glossary#

IMAP

Internet Message Access Protocol. Reads mail that stays on the server, so all your devices see the same inbox, folders and read status.

POP3

Post Office Protocol version 3. Downloads mail to 1 device and can remove it from the server. Older method, still useful for local archives.

SMTP

Simple Mail Transfer Protocol. Sends your outgoing mail. Every account needs it next to IMAP or POP3, which only receive.

SSL / TLS / STARTTLS

Encryption for the connection. SSL/TLS encrypts from the start (ports 993, 995, 465). STARTTLS upgrades a plain connection (port 587).

Secure Mail Key (App Password)

A 16 character code that replaces your real password inside email apps. AT&T's name for what other providers call an app password. Safer because you can revoke 1 key without changing your main password.

OAuth

Sign in through the provider's own window instead of typing a password into the app. The modern method most providers are moving to.

How We Verify These Settings#

Univik builds email backup, migration and converter software since 2013. Our tools sign in to AT&T over IMAP and SMTP every day for thousands of users, so a changed server, port or login rule shows up in our connection logs before most guides notice it.

Every value on this page is confirmed with 3 checks: a live IMAP and SMTP connection from Univik Email Backup, a comparison against AT&T's official documentation and a fresh secure mail key generated through the current myAT&T sign-in flow. We re verify after any provider announcement and at least once a quarter.

Found something that no longer matches what AT&T shows you? Tell us and we will retest and update the page, with the change logged in what changed recently.

Help & Support

Frequently Asked Questions

Use imap.mail.att.net on port 993 with SSL. Sign in with your full email address (any AT&T domain) and a secure mail key. The complete table is in the IMAP settings section.

AT&T blocks regular passwords in email apps that lack OAuth sign in. The password is correct, the method is not. Create a secure mail key and use that 16 character code instead. If webmail at currently.com accepts your password, this is almost certainly your problem.

IMAP for almost everyone. It keeps your phone, computer and webmail in sync. POP3 fits only a single computer setup where you want a local download. Full comparison here.

Yes, identical. All 12 AT&T family domains use the same servers, ports and secure mail key system. Only your username changes. The settings are also identical across iPhone, Android and Windows, only the menus differ, which the client setup guides cover.

No. Secure mail keys show only once. Create a new one at att.com/myatt under Profile → Sign-in info, it takes under a minute. The old key keeps working until you delete it, so your other devices are not affected.

Yes, when you use a secure mail key or OAuth sign in. A key only grants mailbox access, never account management and you can delete a single key at any time without touching your real password. Delete keys for devices you no longer use.

An email client with IMAP downloads mail as it syncs, but a dedicated backup tool is faster and saves standard files you can open anywhere. See how to back up your AT&T mailbox. If you already exported files in another format, an email converter changes them to PST, PDF or whatever your new app opens.

Two usual causes. AT&T requires a secure mail key for every app without OAuth sign in, which broke old setups when the rule arrived. And AT&T deletes existing keys whenever it locks an account, so even a working key can vanish. Either way, the fix is a fresh secure mail key. Check what changed recently.

An email migration tool copies mail directly between the 2 accounts over IMAP. You need the AT&T IMAP settings and a secure mail key for this side, plus the same details for the destination account. Every folder, label and date stays intact.

If setting this up feels risky or you have many accounts to move, our managed email migration service does the entire job for you.

Isolate the problem in 2 steps. First sign in at currently.com: if webmail works, your account and password are fine and the problem is your app, almost always the secure mail key. If webmail fails too, the account is locked or AT&T is having a service issue, so clear the lock at att.com or wait it out. Remember that clearing a lock deletes your keys, so create a fresh one after.
