Email Settings GuideQuick answer: GreenGeeks email runs on cPanel. The server is mail.yourdomain.com for every protocol. IMAP uses port 993 with SSL, POP3 uses port 995 with SSL and SMTP uses port 465 with SSL. Your username is the full address and the mailbox password lets you in you set in cPanel. Your exact values also sit under Connect Devices in cPanel. Mail landing in spam? Fix deliverability.
What Changed Recently#
Login rules shift more often than the server names on any host. Here is the current status for GreenGeeks and what it means for your setup.
Worth knowing
Sign in with the whole address. GreenGeeks turns down a bare mailbox name. Type you@yourdomain.com on the incoming and the outgoing server alike.
Worth knowing
One server name covers every protocol. IMAP, POP3 and SMTP all use mail.yourdomain.com. The account server name from Connect Devices works too and carries a matching certificate.
Worth knowing
Messages cap at 50 MB. GreenGeeks limits a single message to 50 MB at the server. A larger attachment bounces, so share a link for big files.
Before You Begin#
Sort these two items before you start. If you skip them, your email app will reject the connection even when every server value is correct.
1. Create the mailbox
Add the address under Email Accounts in cPanel and choose its password with the Create button. That password is what your apps use.
Where: cPanel then Email Accounts
2. Pull the server and ports
Click Connect Devices next to the address and read the Mail Client Manual Settings box for the server name and secure ports.

About GreenGeeks Mail#
GreenGeeks is an independent web host founded in 2008 and known as an eco friendly provider. It runs on cPanel and puts back more clean energy than it draws, so a mailbox lives on your own hosting server.
GreenGeeks has hosted small business sites since 2008 and matches its energy use with renewable credits several times over. The one thing to know for email is that a single server name, mail.yourdomain.com, covers IMAP, POP3 and SMTP. You sign in with the full address and the mailbox password from cPanel.

GreenGeeks Webmail Login#
You can always read your mail in a browser. The official sign in pages are:
Find Your Settings#
IMAP is live as soon as the mailbox exists, so nothing needs turning on. When you want the exact values for a specific address, GreenGeeks prints them inside cPanel.
- Log in to GreenGeeks and open cPanel.
- Go to the Email section and choose Email Accounts.
- Click Connect Devices in the row for your address.
- Read the Mail Client Manual Settings box for the server name and secure ports for that mailbox.
GreenGeeks IMAP Settings#
IMAP is the incoming choice GreenGeeks recommends. It leaves mail on the server, so a laptop and a phone open the same inbox. Read the exact server name from Connect Devices in cPanel.
| IMAP Server | mail.yourdomain.com | |
| Port | 993 | |
| Encryption | SSL/TLS (required) | |
| Username | Your full email address, including @yourdomain.com | |
| Password | Your mailbox password | |
| Authentication | Required |
GreenGeeks 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 | mail.yourdomain.com | |
| Port | 995 | |
| Encryption | SSL/TLS (required) | |
| Username | Your full email address | |
| Password | Your mailbox password |
GreenGeeks SMTP Settings#
SMTP handles outgoing mail. If you can read mail but not send it, the problem is here.
| SMTP Server | mail.yourdomain.com | |
| Port (SSL) | 465 | |
| Port (STARTTLS) | 587 | |
| Encryption | SSL or STARTTLS (required) | |
| Username | Your full email address | |
| Password | Same as incoming mail | |
| Authentication | Required. Switch on outgoing authentication in the mail client. |
465 with SSL. Most home connections block port 25. Some let you fall back to port 26. Confirm outgoing authentication is on.
Check GreenGeeks IMAP Settings Online#
You don't need to download anything to check GreenGeeks IMAP settings online. This page is the lookup: every value is verified, current and copyable straight from your browser. Not sure your address uses GreenGeeks 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 GreenGeeks webmail, which confirms your address and password work, then confirm an app password exists. If both pass, any email app connects with the tables above.
Look Up IMAP Settings for Any Email Domain#
This page covers GreenGeeks. 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 parts come from the mailbox itself. The username is the whole email address and the password is the one you picked when you made the address in cPanel. A standard GreenGeeks account uses no app password.
Username is the full address
Put in you@yourdomain.com in full, with the part after the at sign. A short name on its own gets refused.
Use the same address on incoming and outgoing.
Password is the mailbox one
This is the password you set under Email Accounts in cPanel, not your GreenGeeks account login. Set a fresh one there if an app keeps rejecting it.
Turn two factor sign in on and cPanel can issue an app password to use in place of it.
Set Up GreenGeeks 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 choose Add Account, then switch on manual setup under Advanced options.
- Pick IMAP and put
mail.yourdomain.comon 993 with SSL for incoming. - Use the same server for outgoing on 465 with SSL.
- Sign in with the full address and mailbox password when Outlook asks.
- Send yourself a quick test to check both directions.
Apple Mail (macOS)
- In Mail choose Add Account, then the Other Mail Account option.
- Enter your name, GreenGeeks address and password, then continue.
- Fill mail.yourdomain.com with SSL on both incoming and outgoing.
- Confirm the secure ports so nothing goes out in the clear.
- Save and let the mailbox load.
iPhone and iPad
- In Settings tap Mail, then Mail Accounts and Add Account.
- Pick Other then Add Mail Account and put in your details.
- Keep IMAP selected and put mail.yourdomain.com in both server fields.
- Leave the secure ports iOS fills, since GreenGeeks expects SSL.
- Tap Save and let iOS run its check.
Android
- Open your mail app and tap Add account, then the Other or IMAP path.
- Enter your address and password. Switch to manual setup if it stalls.
- Incoming is mail.yourdomain.com on 993 with SSL.
- Outgoing is mail.yourdomain.com on 465 with SSL.
- Save and swipe down to fetch your mail.
Thunderbird
- In Thunderbird pick Account Actions and Add Mail Account.
- Type your name, GreenGeeks address and password, then Continue.
- Let the probe run, then check IMAP with SSL is chosen.
- If the probe misses, enter mail.yourdomain.com by hand.
- Choose Done and folders arrive on the first sync.
GreenGeeks Webmail Settings#
Server settings connect your apps. The settings here decide how the mailbox behaves on its own. They live in GreenGeeks webmail, which offers Roundcube or Horde at webmail.yourdomain.com.
Signature
Add one within the webmail preferences. It rides on mail sent from webmail. A desktop app keeps its own signature.
Vacation Auto Reply
Add an autoresponder in cPanel with a start and end date. GreenGeeks sends it from the server, so it runs even when your machine is off.
Filters and Folders
Set up filters under Email Filters in cPanel. A rule on the server files a message ahead of any app pulling it down. A rule inside an app fires only while that app runs.
Spam and Blocked Senders
GreenGeeks runs SpamAssassin on incoming mail. Tune the score and block addresses in cPanel. Flagged mail moves to the junk folder for a look.
POP3 vs IMAP#
| Feature | IMAP | POP3 |
|---|---|---|
| Where mail lives | On the GreenGeeks 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 |
GreenGeeks Sending and Storage Limits#
GreenGeeks sets a few concrete limits worth knowing before you bulk forward or move a mailbox:
| Message size | 50 MB per message |
| Email accounts | Unlimited, except Lite50 |
| Lite50 plan | Capped at 50 accounts |
| Mailbox storage | Set by your hosting plan |
| Secure webmail port | 2096 |
| Oversized message | Bounces, so share a link |
Troubleshooting GreenGeeks 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 as the username with the mailbox password from cPanel, not the account login. |
| Message too large | Attachment over the 50 MB cap | GreenGeeks bounces a message above 50 MB. Send a shared link for large files instead. |
| 550 5.7.1 message blocked | Outbound filter flagged the message | Open the link in the bounce and mark it a false positive if the mail is genuine. Set up SPF and DKIM to cut repeats. |
| Mail keeps landing in spam | SPF or DKIM missing | Run Email Deliverability Repair in cPanel to add both records. Allow up to 48 hours for the change to spread. |
| Cannot connect to server | Wrong port or encryption | Set 993 with SSL in and 465 with SSL out. A firewall on the machine can also block it. |
| Repeated password prompt | Short username or a typo | Clear the saved login, then enter 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. |
Reader Reported Fixes
Copy the values from Connect Devices. When a manual setup will not connect, the Mail Client Manual Settings box in cPanel prints the exact server name and ports for that mailbox. Pasting those in removes the guesswork that trips most setups.
Enter the whole email address. A rejected login on GreenGeeks usually traces to a short username. The username has to be the full you@yourdomain.com address on both incoming and outgoing.
Keep Your Mail Out of Spam#
Sending works, yet the mail lands in a junk folder or bounces. On GreenGeeks two things fix that. First, set up the records that prove your mail is yours. Second, understand the filter that checks every message on the way out.
Turn on SPF and DKIM
Open cPanel, go to the Email section and choose Email Deliverability. Pick your domain and select Repair. GreenGeeks then writes an SPF record that lists the servers allowed to send for your domain. It also adds a DKIM key that signs each outgoing message. The same screen shows your PTR reverse DNS status. For a cPanel mailbox this happens with a couple of clicks.
SPF proves the server
The record names the IP addresses allowed to send for your domain. A receiving server checks it before accepting the mail. A missing or wrong SPF record is a common reason mail is refused.
DKIM proves the message
A signature in the headers and DNS shows the message was not changed on the way. Together with SPF it lifts your mail past most spam checks.
Moving Mail In or Out?#
GreenGeeks mail speaks plain IMAP, so a mailbox moves in or out like any cPanel account. Every folder stays on the server until the move wraps up.
Take a copy first. Back up the mailbox ahead of a move. A note that arrives during the switch can sit on either side. A copy keeps you covered.
Carrying mail across? The Univik Email Migration Tool moves each folder across over IMAP. Give it your GreenGeeks server name and mailbox password on the GreenGeeks side and the other account opposite.
Rather delegate it? Our Email Migration Services team handles 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 GreenGeeks 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 GreenGeeks from the source list. If it isn't listed by name, choose IMAP.
- Give the whole email address with your mailbox password. The bit after the at sign has to be included.
- When the tool wants server details, give mail.yourdomain.com on port 993 with SSL for the GreenGeeks side., use mail.yourdomain.com on port
993with SSL, straight from the IMAP table above. - 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 Backup
Download your complete GreenGeeks mailbox to PST, MBOX, EML or PDF before switching or closing the account.
Email Backup Tool →
Email Migration Tool
Copy every folder from GreenGeeks straight into Gmail, Microsoft 365 or any other account. No manual export needed.
Email Migration Tool →
Email Converter Tool
Already have MBOX, EML or OST files from an old export? Convert them to PST, PDF or any format your new app opens.
Email Converter Tool →Prefer to hand the whole migration to experts?
If the server names and passwords feel fiddly, the automatic route saves the effort. Univik's migration team handles the complete project: planning, transfer, verification and a report showing every folder made it. Since 2013, for single mailboxes up to full company moves.
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).
App Password
A code a mail app uses instead of your real password. GreenGeeks needs one only after you switch on two factor sign in.
Connect Devices
The cPanel button beside each address that opens the Mail Client Manual Settings box with your exact server name and ports.
cPanel
The control panel GreenGeeks uses for hosting email. You create mailboxes, set passwords and read settings here.
Roundcube and Horde
The two webmail apps GreenGeeks offers in a browser at webmail.yourdomain.com for reading mail without a desktop client.
Mail Client Manual Settings
The box inside Connect Devices that lists the exact server name and secure ports for a specific mailbox to copy into an app.
Message Size Limit
The 50 MB ceiling GreenGeeks puts on a single message at the server. A larger one bounces before it sends.
SpamAssassin
The cPanel spam filter. Adjust its score and block addresses from the GreenGeeks mail tools.
Two Factor Authentication
A second login step beyond the password. GreenGeeks keeps it off unless you enable it in cPanel, which then wants an app password.
SPF
A DNS record naming the servers allowed to send for your domain. GreenGeeks writes it from the Email Deliverability tool.
DKIM
A signature added to your DNS and message headers. It shows a message was not altered on the way to the recipient.
Email Deliverability
The cPanel screen that creates SPF and DKIM records and shows PTR status. Its Repair button sets both up for a domain.
How We Verify These Settings#
Univik builds email backup, migration and converter software since 2013. Our tools sign in to GreenGeeks 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 GreenGeeks knowledge base 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 GreenGeeks 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
Point it at mail.yourdomain.com on port 993 with SSL. The username is your full email address and the password is the mailbox password from cPanel. Your exact values also appear under Connect Devices. The IMAP settings section holds every value.
Check the username first. It has to be the full address, not the short name before the at sign. GreenGeeks uses an app password only when you have switched on two factor sign in. Otherwise the mailbox password is correct.
IMAP suits nearly everyone and GreenGeeks recommends it. Your mail stays on the server so every device matches. POP3 pulls mail down to one machine and can lose it if that machine dies. Full comparison here.
Yes. The server, ports and encryption stay the same on iPhone, Android and Windows. The path to the settings screen shifts by app, which the client setup guides spell out.
GreenGeeks caps a single message at 50 MB on the server. A bigger attachment bounces before it leaves. Share a cloud link for large files. You can also split the attachment across separate messages.
Yes. Leave SSL on for each server so the login is never sent in the open. GreenGeeks runs on renewable energy. Two factor sign in from cPanel adds a second layer if you want it.
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 GreenGeeks mailbox. If you already exported files in another format, an email converter changes them to PST, PDF or whatever your new app opens.
On cPanel the usual causes are a short username, a wrong password or a blocked port. Check what to know. Use the full address, the mailbox password, then 993 in and 465 out with SSL.
A migration tool shifts mail between the two accounts over IMAP. Give the GreenGeeks IMAP settings with the mailbox password on this side and the destination details on the other. Each folder keeps its dates through the move.
If setting this up feels risky or you have many accounts to move, our managed email migration service does the entire job for you.
The usual cause is a missing SPF or DKIM record. Open cPanel, go to Email Deliverability and select Repair for your domain, which adds both. GreenGeeks also runs an outbound filter on every message, so a genuine mail that bounces with 550 5.7.1 can be marked a false positive through the link in the bounce. An SPF change can take up to 48 hours to spread.
