Email Settings GuideQuick answer: Interia email runs on Interia. Every protocol connects to poczta.interia.pl. IMAP is on 993, POP3 on 995 and SMTP on 465, each secured with SSL. Your username is the full address and the mailbox password you set in Interia settings lets you in. Your exact values also sit under One Server Name in Interia settings. On @poczta.fm or @int.pl? the server is still poczta.interia.pl.
What Changed Recently#
A host changes how you sign in more often than it changes the server names. Here is the current status for Interia and what it means for your setup.
Worth knowing
Use the full address. Interia turns down a bare mailbox name in most clients. Put you@interia.pl (or your own ending) in both the incoming and the outgoing server.
Worth knowing
One name for reading and sending. poczta.interia.pl is the incoming server and the outgoing server both. There is no separate smtp host to set.
Worth knowing
Send on 465 or 587. The outgoing side takes port 465 with SSL. Port 587 with STARTTLS works too. Match the security to the port you pick.
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 Interia settings and set its password. That password is the one your apps use.
Where: Interia then your mail settings
2. Open the one server name
Click the poczta.interia.pl server next to the address, then the one server name to read the server name and secure ports.
Where: One Server Name
About Interia Poczta#
Interia Poczta is the free mail of Interia.pl, one of Poland's large web portals. A mailbox reads in a browser at poczta.interia.pl and works in Outlook, Apple Mail or Thunderbird.
Interia keeps things on one server name. poczta.interia.pl is the incoming server for IMAP on 993 and POP on 995. It is also the outgoing server for SMTP on 465 with SSL. Port 587 with STARTTLS is the alternative. The username is your full address. The password is your normal Interia one. Addresses come in a few endings such as interia.pl, interia.eu and poczta.fm. All of them use this same server.
| Service Name | Interia Poczta, free webmail |
| Run By | Interia.pl, Poland |
| Address Endings | interia.pl, interia.eu, poczta.fm and more |
| Incoming Server | poczta.interia.pl 993 (POP 995) |
| Outgoing Server | poczta.interia.pl, port 465 SSL or 587 STARTTLS |
| Username | Full email address |
| Webmail | poczta.interia.pl |

One Server Name Does Everything#
Most providers give you two server names, an imap one for reading and an smtp one for sending. Interia uses a single name for both. Put poczta.interia.pl in the incoming server and in the outgoing server alike.
| Role | Server name | Port |
|---|---|---|
| Incoming (IMAP) | poczta.interia.pl | 993, SSL |
| Incoming (POP3) | poczta.interia.pl | 995, SSL |
| Outgoing (SMTP) | poczta.interia.pl | 465 SSL or 587 STARTTLS |
Interia IMAP Settings#
IMAP is the incoming choice Interia 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 the one server name in Interia settings.
| IMAP Server | poczta.interia.pl | |
| Port | 993 | |
| Encryption | SSL/TLS (required) | |
| Username | Your full email address, including @interia.pl | |
| Password | Your mailbox password | |
| Authentication | Required |
Interia 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 | poczta.interia.pl | |
| Port | 995 | |
| Encryption | SSL/TLS (required) | |
| Username | Your full email address | |
| Password | Your mailbox password |
Interia SMTP Settings#
SMTP handles outgoing mail. If you can read mail but not send it, the problem is here.
| SMTP Server | poczta.interia.pl | |
| 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 server authentication in the client. |
465 with SSL. Many home connections block port 25. Interia also accepts 587 with STARTTLS. Confirm outgoing authentication is on.
Check Interia IMAP Settings Online#
You don't need to download anything to check Interia IMAP settings online. This page is the lookup: every value is verified, current and copyable straight from your browser. Not sure your address uses Interia 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 Interia webmail, which confirms your address and password work, then confirm an Interia password exists. If both pass, any email app connects with the tables above.
Look Up IMAP Settings for Any Email Domain#
This page covers Interia. 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 Interia settings. A standard Interia mailbox uses no Interia password.
Username is the full address
Type you@interia.pl in full, with the part after the at sign. Interia 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 Interia settings, not your Interia client area login. Reset it there if an app keeps refusing it.
The two factor prompt in the Interia client area guards billing, not the mailbox connection.
Set Up Interia 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
poczta.interia.plon 993 with SSL. - Set outgoing to the same server on 465 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, Interia address and password, then continue.
- Enter poczta.interia.pl 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 poczta.interia.pl in both server boxes.
- Leave the secure ports iOS fills, since Interia 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 poczta.interia.pl on 993 over SSL.
- For outgoing use poczta.interia.pl on 465 over SSL.
- Save and swipe down to fetch your mail.
Thunderbird
- In Thunderbird pick Account Actions, then Add Mail Account.
- Type your name, Interia address and password, then Continue.
- Wait for detection, then make sure IMAP with SSL is picked.
- If detection fails, type poczta.interia.pl in yourself.
- Hit Done and the folders fill in on the first sync.
Interia Webmail Settings#
Server settings connect your apps. The controls here shape how the mailbox acts on its own. They live in Interia webmail, opened at poczta.interia.pl 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 Interia settings and give it start and end dates. The Interia server delivers it, so it fires even when your machine is off.
Filters and Folders
Create filters from the Interia webmail filters in Interia settings. 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
Interia runs SpamAssassin on incoming mail. Set the threshold and block unwanted senders in Interia settings. Flagged mail lands in the junk folder for a look.
POP3 vs IMAP#
| Feature | IMAP | POP3 |
|---|---|---|
| Where mail lives | On the Interia 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 |
Interia Poczta at a Glance#
Every value for an interia.pl address in one place. Note that one name serves every role:
| Incoming (IMAP) | poczta.interia.pl, port 993, SSL |
| Incoming (POP3) | poczta.interia.pl, port 995, SSL |
| Outgoing (SMTP) | poczta.interia.pl, port 465 SSL or 587 STARTTLS |
| Authentication | Required, same login as incoming |
| Username | Full email address |
| Webmail | poczta.interia.pl |
Troubleshooting Interia 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 Interia, not the client area login. |
| Cannot send on port 25 | ISP blocks the default SMTP port | Switch outgoing to 465 with SSL. Interia also accepts 587 with STARTTLS. |
| Cannot find the outgoing server | Looking for an smtp.interia.pl host | Interia does not use a separate smtp name. The outgoing server is poczta.interia.pl, the same as the incoming one, on port 465 with SSL. Turn authentication on with the same login. |
| Sending is refused on the outgoing server | Port and security do not match | On poczta.interia.pl, port 465 pairs with SSL and port 587 pairs with STARTTLS. Set one matched pair, keep authentication on, then a test message goes out. |
| Cannot connect to server | Wrong port or encryption | Set 993 with SSL incoming and 465 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. |
| poczta.fm or int.pl address will not connect | Client set to a poczta.fm server | These are Interia mailboxes, so there is no poczta.fm or int.pl server. Set both the incoming and the outgoing server to poczta.interia.pl, then sign in with your full address as it stands. |
| Unsure which server a chosen ending needs | Every ending shares one server | interia.pl, interia.eu, poczta.fm and int.pl all use poczta.interia.pl. Use it for the incoming and the outgoing server whichever ending you picked at sign-up. |
Reader Reported Fixes
Copy from the one server name. When a manual setup will not connect, the the one server name page in Interia settings 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 webpoczta.interia.pl with the full address and mailbox password. If webmail works, the credentials are right and the issue sits in the app settings.
The Interia Endings You Can Pick#
Interia does not tie you to interia.pl. When you sign up, you choose an address ending from a menu, so two Interia mailboxes can look quite different at the end. The server settings do not change with the choice.
Alongside interia.pl, the sign-up page offers endings such as interia.eu, poczta.fm and int.pl, with more shown as available to register. Whichever one you picked, the incoming and outgoing server is poczta.interia.pl on the usual ports. The username is your full address with that ending. There is no per-ending server to hunt for.
| Your address ends in | Server to use |
|---|---|
| interia.pl | poczta.interia.pl |
| interia.eu or poczta.fm | The same, poczta.interia.pl |
| int.pl or another Interia ending | The same again, poczta.interia.pl |
Moving Mail In or Out?#
Interia mail speaks plain IMAP, so a mailbox moves in or out like any Interia 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 Interia 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 Interia 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 Interia 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 poczta.interia.pl on port 993 with SSL for Interia. 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.

Email Settings Glossary#
IMAP
Internet Message Access Protocol. Reads mail that stays on the Interia server, so every device shows the same inbox. Use poczta.interia.pl on port 993 with SSL.
POP3
Post Office Protocol version 3. Downloads mail to one device. Use poczta.interia.pl on port 995 with SSL if you prefer POP. The host name is the same.
SMTP
Simple Mail Transfer Protocol. Sends your outgoing mail through poczta.interia.pl on port 465 with SSL. It needs a sign-in with your address and password.
SSL and TLS
The encryption Interia uses on 993, 995 and 465. Keep it on so your sign-in and mail stay private.
poczta.interia.pl
The one Interia server name. It is the incoming server for IMAP and POP. It is the outgoing server for SMTP as well. There is no separate imap or smtp host.
One Server Name
The Interia pattern. Rather than an imap host and an smtp host, a single poczta.interia.pl answers for reading and for sending alike.
Full Email Address
Your username for the server is the whole address, like you@interia.pl or you@interia.eu. The same value works for incoming and outgoing.
SMTP Authentication
The server-requires-authentication setting on poczta.interia.pl. Turn it on with the same login as the incoming server, so Interia lets your mail out.
Interia Webmail
The browser view of your mail at poczta.interia.pl. Handy for a quick check and for confirming your password before you set up a client.
interia.eu and poczta.fm
Other Interia address endings alongside interia.pl. Whichever ending your address has, it uses the same poczta.interia.pl server.
Port 465 or 587
Two ways to send on poczta.interia.pl. Port 465 pairs with SSL, port 587 with STARTTLS. Pick one and match the security to it.
Interia Poczta
The free mail of Interia.pl, a large Polish web portal. Its addresses read and send through the single poczta.interia.pl server.
Available Endings
The menu of address endings Interia offers at sign-up, interia.pl, interia.eu, poczta.fm and int.pl among them. You choose one for your address.
int.pl and poczta.fm
Two of the endings you can register alongside interia.pl. They are Interia mailboxes, so they use poczta.interia.pl like the rest.
Same Server, Any Ending
The rule that ties it together. The ending you picked does not change the settings. Every Interia address reads and sends on poczta.interia.pl.
How We Verify These Settings#
Univik builds email backup, migration and converter software since 2013. Our tools sign in to Interia 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 Interia 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 Interia shows you? Tell us and we will retest and update the page, with the change logged in what changed recently.

Frequently Asked Questions
Interia uses one server name for everything. poczta.interia.pl is the incoming server on 993 for IMAP or 995 for POP. It is also the outgoing server on 465 with SSL. The username is your full address. Turn authentication on for sending.
It is poczta.interia.pl, the same name as the incoming server. There is no separate smtp.interia.pl. Send on port 465 with SSL. Port 587 with STARTTLS works too. Keep authentication on with the same login as the incoming server.
Almost always the port and the security do not match. On poczta.interia.pl, port 465 goes with SSL and port 587 goes with STARTTLS. Set one matched pair, keep authentication on, then a test message goes out.
IMAP is the better default. It keeps mail on the Interia 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@interia.pl or you@interia.eu, not the part before the at sign. The same value goes in the incoming and the outgoing server.
Yes. Interia addresses come in a few endings such as interia.pl, interia.eu and poczta.fm. Every one uses poczta.interia.pl. Only the ending of your address differs, so point either one at the same server.
Reading is 993 for IMAP or 995 for POP, both with SSL. Sending is 465 with SSL. Port 587 with STARTTLS is the other option. All of them run on the one poczta.interia.pl server with authentication on.
Open poczta.interia.pl and sign in with your full address and password. Webmail is the quickest way to check mail without a client. It also confirms your password before you set one up.
Yes. An interia.pl mailbox reads over IMAP and sends over SMTP at no charge, all on poczta.interia.pl. Set that one server name in your client, then sign in with your full address and your Interia password.
poczta.interia.pl, the same as any Interia address. interia.pl, interia.eu, poczta.fm and int.pl are all Interia endings that read and send on the one server, so there is no poczta.fm or int.pl server to look for. Put poczta.interia.pl in the incoming and the outgoing server. Use your full address with its own ending as the username.
