Email Settings GuideQuick answer: UOL email runs on UOL. Every protocol connects to imap.uol.com.br. IMAP is on 993, POP3 on 995 and SMTP on 587, each secured with SSL. Your username is the full address and the mailbox password you set in your UOL account lets you in. Your exact values also sit under Paid Subscription in your UOL account. Reads but will not send? check the outgoing server.
What Changed Recently#
A host changes how you sign in more often than it changes the server names. Here is the current status for UOL and what it means for your setup.
Worth knowing
Use the full address. UOL turns down a bare mailbox name in most clients. Put you@uol.com.br in both the incoming and the outgoing server.
Worth knowing
The outgoing name has an extra s. Sending uses smtps.uol.com.br, not smtp.uol.com.br. Miss the s and the send fails.
Worth knowing
A subscription keeps it working. A @uol.com.br mailbox needs an active paid UOL plan. Let it lapse and the mailbox stops.
Before You Begin#
Handle these two basics before anything else. Skip them and your email app will reject the connection even when every server value is correct.
1. Create the mailbox
Add the address under your mail settings in your UOL account and set its password. That password is the one your apps use.
Where: UOL then your mail settings
2. Open your UOL mail settings
Click the subscription your mailbox needs next to the address, then your UOL mail settings to read the server name and secure ports.
Where: Paid Subscription
About UOL Mail#
UOL Mail is the email of Universo Online, one of Brazil's largest internet portals since 1996. A mailbox reads in a browser at email.uol.com.br. It also works in Outlook, Apple Mail or Thunderbird.
Incoming mail uses imap.uol.com.br on 993 with SSL. Outgoing uses smtps.uol.com.br on 587. The extra s in that name matters. The username is your full address. Two points catch people out. A @uol.com.br mailbox comes with a paid UOL subscription rather than a free sign-up. The outgoing server is smtps.uol.com.br, not smtp.uol.com.br. BOL Mail is UOL's sister service and uses its own bol.com.br servers.
| Service Name | UOL Mail, part of a UOL subscription |
| Run By | UOL, Universo Online, Brazil |
| Address Domain | uol.com.br (sister service BOL uses bol.com.br) |
| Incoming Server | imap.uol.com.br 993 (POP pop.uol.com.br 995) |
| Outgoing Server | smtps.uol.com.br, port 587 (465 with SSL) |
| Before you start | An active paid UOL subscription |
| Username | Full email address |
| Webmail | email.uol.com.br |
UOL Webmail Login#
You can always read your mail in a browser. The official sign in pages are:
UOL Mail Is a Paid Subscription#
A @uol.com.br address is not free webmail. It comes with a paid UOL subscription, so the mailbox works in an app or the webmail only while that subscription is active. If a client stops connecting, check the plan first.
| Account | What it costs | Servers |
|---|---|---|
| UOL Mail | Part of a paid UOL subscription | imap.uol.com.br, smtps.uol.com.br |
| BOL Mail | Its own paid plan, UOL's sister email | bol.com.br servers |
| Lapsed plan | Mailbox stops working | Renew to restore access |
UOL IMAP Settings#
IMAP is the incoming choice UOL points most people to. Mail stays put on the server, so a laptop and a phone read one shared inbox. Pull the exact server name from your UOL mail settings in your UOL account.
| IMAP Server | imap.uol.com.br | |
| Port | 993 | |
| Encryption | SSL/TLS (required) | |
| Username | Your full email address, including @uol.com.br | |
| Password | Your mailbox password | |
| Authentication | Required |
UOL 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.
| POP3 Server | pop.uol.com.br | |
| Port | 995 | |
| Encryption | SSL/TLS (required) | |
| Username | Your full email address | |
| Password | Your mailbox password |
UOL SMTP Settings#
SMTP handles outgoing mail. If you can read mail but not send it, the problem is here.
| SMTP Server | smtps.uol.com.br | |
| Port (SSL) | 587 | |
| Port (STARTTLS) | 587 | |
| Encryption | SSL or STARTTLS (required) | |
| Username | Your full email address | |
| Password | Same as incoming mail | |
| Authentication | Required. Switch on outgoing server authentication in the client. |
587 with SSL. Many home connections block port 25. UOL also supports 587 and 26 if 587 is blocked. Confirm outgoing authentication is on.
Check UOL IMAP Settings Online#
You don't need to download anything to check UOL IMAP settings online. This page is the lookup: every value is verified, current and copyable straight from your browser. Not sure your address uses UOL servers? 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? Sign in at UOL webmail, which confirms your address and password work, then confirm an UOL password exists. If both pass, any email app connects with the tables above.
Look Up IMAP Settings for Any Email Domain#
This page covers UOL. For every other address, work email on a company domain included, we run a free online lookup database: imapsettings.com.
imapsettings.com
Complete email settings database, by Univik
Enter any email address and get the incoming and outgoing server settings for that domain in 1 step:
Your address is used only to find the settings for that domain. Nothing is stored or shared.
Username and Password#
Both come from the mailbox itself. The username is the whole email address and the password is the one you chose when you built the address in your UOL account. A standard UOL mailbox uses no UOL password.
Username is the full address
Type you@uol.com.br in full, with the part after the at sign. UOL turns down a bare mailbox name.
Put that same address on both incoming and outgoing.
Password is the mailbox one
This is the webmail password you set under your mail settings in your UOL account, not your UOL client area login. Reset it there if an app keeps refusing it.
The two factor prompt in the UOL client area guards billing, not the mailbox connection.
Set Up UOL in Email Clients#
The servers and ports are always the same. Only the menus differ. Jump to your app:
Outlook (Windows and Mac)
- In Outlook select Add Account, then turn on manual setup under Advanced options.
- Choose IMAP and set incoming to
imap.uol.com.bron 993 with SSL. - Set outgoing to the same server on 587 with SSL.
- Enter the full address and mailbox password when Outlook prompts you.
- Send a test message to yourself to prove both paths.
Apple Mail (macOS)
- In Mail select Add Account, then pick Other Mail Account.
- Give your name, UOL address and password, then continue.
- Enter imap.uol.com.br with SSL on incoming and outgoing.
- Keep the SSL ports so nothing sends in plain text.
- Save and wait for the mailbox to load.
iPhone and iPad
- In Settings open Mail, then tap Mail Accounts and Add Account.
- Tap Other then Add Mail Account and fill your details.
- Keep IMAP chosen and put imap.uol.com.br in both server boxes.
- Leave the secure ports iOS fills, since UOL expects SSL.
- Tap Save and let iOS run its check.
Android
- Open your mail app and tap Add account, then Other or IMAP.
- Put in your address and password. Switch to manual setup if it stalls.
- For incoming use imap.uol.com.br on 993 over SSL.
- For outgoing use smtps.uol.com.br on 587 over SSL.
- Save and swipe down to fetch your mail.
Thunderbird
- In Thunderbird pick Account Actions, then Add Mail Account.
- Type your name, UOL address and password, then Continue.
- Wait for detection, then make sure IMAP with SSL is picked.
- If detection fails, type imap.uol.com.br in yourself.
- Hit Done and the folders fill in on the first sync.
UOL Webmail Settings#
Server settings connect your apps. The controls here shape how the mailbox acts on its own. They live in UOL webmail, opened at email.uol.com.br in any browser.
Signature
Add one in the webmail preferences. It rides on mail sent from webmail. A desktop app keeps a signature of its own.
Vacation Auto Reply
Set an autoresponder in your UOL account and give it start and end dates. The UOL server delivers it, so it fires even when your machine is off.
Filters and Folders
Create filters from the UOL webmail filters in your UOL account. A server side rule sorts a message ahead of any device fetching it. A rule set inside an app only works while that app is running.
Spam and Blocked Senders
UOL runs SpamAssassin on incoming mail. Set the threshold and block unwanted senders in your UOL account. Flagged mail lands in the junk folder for a look.
POP3 vs IMAP#
| Feature | IMAP | POP3 |
|---|---|---|
| Where mail lives | On the UOL server | Downloaded to 1 device |
| 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 |
UOL Mail at a Glance#
Every value for a uol.com.br address in one place. Keep the subscription active:
| Incoming (IMAP) | imap.uol.com.br, port 993, SSL |
| Incoming (POP3) | pop.uol.com.br, port 995, SSL |
| Outgoing (SMTP) | smtps.uol.com.br, port 587 |
| SMTP with SSL | Port 465 with SSL on |
| Authentication | Required, same login as incoming |
| Account | Active paid UOL subscription |
| Username | Full email address |
| Webmail | email.uol.com.br |
Troubleshooting UOL Connections#
Find the exact error your email app shows, then apply the fix:
| Error you see | What it means | Fix |
|---|---|---|
| Username or password rejected | Short username or wrong password | Use the full email address with the mailbox password from UOL, not the client area login. |
| Cannot send on port 25 | ISP blocks the default SMTP port | Switch outgoing to 587 with SSL. UOL also accepts 587 and 26 if 587 is blocked. |
| Mailbox stopped working | The UOL subscription lapsed | A @uol.com.br address needs an active paid UOL plan. Check the subscription in your UOL account and renew it if needed. Once it is active again, the mailbox and the client both work. |
| Reads mail but will not send | Outgoing server set to smtp not smtps | The UOL outgoing server is smtps.uol.com.br with an extra s. Set that on port 587, turn authentication on with the same login as incoming, then a test message goes out. Port 465 works with SSL on. |
| Cannot connect to server | Wrong port or encryption | Set 993 with SSL incoming and 587 with SSL outgoing. A firewall on your own machine can block it as well. |
| Repeated password prompt | Short username or a typo | Clear the saved login, then put in the full address with the mailbox password. |
| Messages stuck in Outbox | SMTP authentication is off | Enable "outgoing server requires authentication" with the same login as incoming mail. |
| Password refused only when sending | SPA is ticked | UOL does not use Secure Password Authentication. Untick that box in the outgoing-server settings, keep the server set to require authentication with the same login as incoming, then send a test on smtps.uol.com.br. |
| Client asks for a separate outgoing password | Same-as-incoming option is off | The outgoing server uses the same login as the incoming one. Turn on the option to use the same settings as the incoming server, so you do not enter a second password for smtps.uol.com.br. |
Reader Reported Fixes
Copy from your UOL mail settings. When a manual setup will not connect, the your UOL mail settings page in your UOL account prints the exact server name and ports for that mailbox. Pasting those in clears the guesswork behind most failed setups.
Test the login in webmail first. Sign in at webimap.uol.com.br with the full address and mailbox password. If webmail works, the credentials are right and the issue sits in the app settings.
Getting UOL Mail to Send#
Reading UOL mail rarely causes trouble. Sending trips more people up, because the outgoing server needs four things right. Miss any one and the client reads mail but refuses to send.
Start with the name. The outgoing server is smtps.uol.com.br, with an s after smtp, on port 587. Port 465 works when you turn SSL on. Then open the outgoing-server settings and tick that the server requires authentication, keeping the option to use the same login as the incoming server. The one to watch is Secure Password Authentication, often shown as SPA. UOL's own guide says to leave it unticked. Ticking it is a common reason a correct password is refused on the way out.
| Setting | Value |
|---|---|
| Outgoing server | smtps.uol.com.br, the s after smtp matters |
| Outgoing port | 587 (or 465 with SSL turned on) |
| Requires authentication | On, with the same login as the incoming server |
| Secure Password (SPA) | Leave it unticked |
Moving Mail In or Out?#
UOL mail speaks plain IMAP, so a mailbox moves in or out like any UOL account. Each folder stays on the server until the move finishes.
Take a copy first. Back up the mailbox before a move. A note that arrives mid switch can sit on either side. A copy keeps you safe.
Carrying mail across? The Univik Email Migration Tool moves each folder over an IMAP link. Give it the UOL server name and mailbox password on this side and the other account opposite.
Rather hand it off? Our Email Migration Services team runs the whole move and verifies each folder arrived.
Use These Settings in Univik Email Backup#
The same IMAP settings above let you download your complete UOL 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 UOL from the source list. If it isn't listed by name, choose IMAP.
- Give the complete email address with your mailbox password. The login name is always the whole email address.
- When the backup tool wants server details, hand it imap.uol.com.br on port 993 with SSL for UOL. Take those values straight from the IMAP table above, with port
993over SSL. - Pick a saving format and folder, then start the backup. Large mailboxes download in the background.
Univik Tools That Use These Settings#
Many people land here while migrating or archiving a mailbox. All 3 tools use the same IMAP settings from this page:

Email Settings Glossary#
IMAP
Internet Message Access Protocol. Reads mail that stays on the UOL server, so every device shows the same inbox. Use imap.uol.com.br on port 993 with SSL.
POP3
Post Office Protocol version 3. Downloads mail to one device. Use pop.uol.com.br on port 995 with SSL if you prefer POP.
SMTP
Simple Mail Transfer Protocol. Sends your outgoing mail through smtps.uol.com.br on port 587. It needs a sign-in with your address and password.
SSL and TLS
The encryption UOL uses. Keep it on for imap.uol.com.br on 993. On smtps.uol.com.br use 587. Port 465 works with SSL on.
imap.uol.com.br
The incoming server for IMAP. Set it on port 993 with SSL to read mail that stays on the server.
smtps.uol.com.br
The outgoing server. Note the extra s, smtps not smtp. Set it on port 587 with a sign-in to send your mail.
UOL Subscription
The paid UOL plan a @uol.com.br mailbox comes with. Without an active subscription the address does not work in an app or the webmail.
BOL Mail
UOL's sister email service. A @bol.com.br mailbox is its own paid plan and uses its own bol.com.br servers, not the uol.com.br ones.
UOL Mail Webmail
The browser view of your mail at email.uol.com.br. Handy for a quick check without a client set up.
Full Email Address
Your username for the server is the whole address, like you@uol.com.br. The same value works for incoming and outgoing.
SMTP Authentication
The my-server-requires-authentication setting on smtps.uol.com.br. Turn it on with the same login as the incoming server, so UOL lets your mail out.
UOL
Universo Online, one of Brazil's largest internet portals since 1996. Its mail runs on imap.uol.com.br and smtps.uol.com.br for subscribers.
Secure Password Authentication
Often shown as SPA, a Windows sign-in method UOL does not use. Leave the box unticked, since ticking it makes UOL refuse a correct password on the way out.
Use Same Settings as Incoming
The outgoing-server option that tells the client to send with the same login as the incoming server. Keep it on, so the outgoing side signs in the same way.
Port 465
The alternate outgoing port for UOL. Use it with SSL turned on when 587 is blocked. Both ports go through smtps.uol.com.br.
How We Verify These Settings#
Univik builds email backup, migration and converter software since 2013. Our tools sign in to UOL 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 three checks: a live IMAP and SMTP connection from Univik Email Backup, a comparison against the UOL guides and a sign in with a real mailbox using the full address. We re verify after any provider announcement and at least once a quarter.
Found something that no longer matches what UOL 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
Incoming is imap.uol.com.br on port 993 with SSL. For POP the host is pop.uol.com.br on port 995. Outgoing is smtps.uol.com.br on port 587, with the extra s in the name. Port 465 works with SSL on. The username is your full address.
No. A @uol.com.br mailbox comes with a paid UOL subscription, so it works only while the plan is active. BOL Mail is UOL's sister email on its own paid plan. Neither is a free sign-up like some other portals.
A lapsed subscription is the usual reason. The mailbox needs an active paid UOL plan, so a client and the webmail both stop when the plan ends. Check the subscription in your UOL account and renew it, then the mailbox works again.
The outgoing server is most likely set to smtp.uol.com.br. UOL uses smtps.uol.com.br, with an extra s. Set that on port 587, turn authentication on with the same login as incoming, then send a test. Port 465 works with SSL on.
IMAP is the better default. It keeps mail on the UOL server so a phone and a laptop show the same inbox. POP downloads to one device, which suits a single machine you back up yourself.
Your username is the full address, like you@uol.com.br. The same value goes in the incoming and the outgoing server. A BOL address uses the whole @bol.com.br address the same way.
Send through smtps.uol.com.br on port 587. Note the extra s in the name. Turn authentication on with the same login as the incoming server. Port 465 works too when you switch SSL on.
BOL Mail is UOL's sister service. A @bol.com.br mailbox is its own paid plan and uses its own servers on bol.com.br, not the uol.com.br ones. Point every server at the bol.com.br names if your address ends in bol.com.br.
Open email.uol.com.br and sign in with your full address and password. Webmail is the quickest way to check mail without a client set up, as long as your UOL subscription is active.
Set the outgoing server to smtps.uol.com.br, with the s after smtp, on port 587. Port 465 works with SSL turned on. In the outgoing-server settings, tick that the server requires authentication and keep the option to use the same login as the incoming server. Leave Secure Password Authentication, shown as SPA, unticked. With those four in place a test message goes out.
