Email Settings GuideQuick answer: Telenet mail uses imap.telenet.be on 993 for IMAP or pop.telenet.be on 995 for POP3, each over SSL. Sending is smtp.telenet.be on 587 with STARTTLS and authentication. Sign in with your full telenet.be address and your Telenet mailbox password. Port 465 with SSL works too if 587 is blocked. Want mail to go out from a chosen alias? Here is how.
What Changed Recently#
Telenet mail follows a mailbox model worth knowing before you set up an app. Here is the current status and what a telenet.be address needs.
Worth knowing
Telenet recommends IMAP. It keeps your mail on the server, so every device shows the same inbox.
Worth knowing
One mailbox, up to five addresses. A Telenet mailbox carries one main address plus four aliases. Every alias uses the same mailbox password.
Worth knowing
Sending needs authentication. Turn on the outgoing server login and pick secure password verification in your app.
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. A Telenet address and password
Your address is you@telenet.be and the password is the one for your Telenet mailbox. The same password covers any aliases.
Where: Telenet Webmail
2. Secure password verification
Telenet asks apps to use secure password verification on incoming and outgoing. Most apps set this on their own.

About Telenet#
Telenet is the largest cable provider in Flanders, part of the Liberty Global group. Its email runs on telenet.be with webmail and standard IMAP, POP3 and SMTP access.
Telenet has offered internet and TV across Flanders since the 1990s and provides a telenet.be mailbox with every residential subscription. The point to remember is the mailbox model. One mailbox can hold up to five equal addresses, one main account and four aliases. They all land in the same inbox and share one password.

Telenet Webmail Login#
You can always read your mail in a browser. The official sign in pages are:
Find Your Settings#
Telenet fills the settings in for most apps. Incoming is imap.telenet.be or pop.telenet.be, while sending goes through smtp.telenet.be. Here are the exact values.
- Open your email app and add a new account.
- Choose IMAP on 993 or POP3 on 995.
- Set incoming to imap.telenet.be with SSL.
- Set outgoing to smtp.telenet.be on 587 with STARTTLS and a login.
Telenet IMAP Settings#
IMAP keeps a Telenet mailbox in sync. Mail stays on the server, so a laptop and a phone read one shared inbox. The incoming host is imap.telenet.be over 993.
| IMAP Server | imap.telenet.be | |
| Port | 993 | |
| Encryption | SSL/TLS (required) | |
| Username | Your full telenet.be address | |
| Password | Your mailbox password | |
| Authentication | Required |
Telenet 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.telenet.be | |
| Port | 995 | |
| Encryption | SSL/TLS (required) | |
| Username | Your full email address | |
| Password | Your mailbox password |
Telenet SMTP Settings#
SMTP handles outgoing mail. If you can read mail but not send it, the problem is here.
| SMTP Server | smtp.telenet.be | |
| Port (STARTTLS) | 587 | |
| Port (SSL) | 465 | |
| Encryption | STARTTLS on 587 (SSL on 465) | |
| Username | Your full telenet.be address | |
| Password | Your Telenet mailbox password | |
| Authentication | Required. Turn on outgoing authentication with secure password verification. |
465 with SSL. Many home connections block port 25. Telenet uses 587 with STARTTLS. Port 465 with SSL works too if 587 is blocked. Confirm outgoing authentication is on.
Check Telenet Settings Online#
You don't need to download anything to check Telenet settings online. This page is the lookup: every value is verified, current and copyable straight from your browser. Not sure your address is a telenet.be one? Type it below to check in a moment.
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 Telenet Webmail, which confirms your address and password work. If webmail opens, any email app connects with the tables above.
Look Up IMAP Settings for Any Email Domain#
This page covers Telenet. 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 your Telenet mailbox. The username is your full telenet.be address. The password is your Telenet mailbox password, the same one for webmail and every alias. There is no separate app password.
Username is the full address
Type your full telenet.be address in, with the part after the at sign. A bare mailbox name is turned down.
Put that same address on both incoming and outgoing.
Password is the mailbox one
This is your Telenet mailbox password, set in Telenet Webmail or My Telenet. Reset it there if an app keeps refusing it.
The mailbox password is the same for the main address and every alias, so one password is all you manage.
Set Up Telenet 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.telenet.beon 993 with SSL. - Set outgoing to
smtp.telenet.beon 587 with STARTTLS and a login. - 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, telenet.be address and password, then continue.
- Enter imap.telenet.be for incoming and smtp.telenet.be for 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.telenet.be for incoming with smtp.telenet.be for outgoing.
- Leave the secure ports iOS fills, since Telenet expects encryption.
- 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.telenet.be on 993 over SSL.
- For outgoing use smtp.telenet.be on 587 with STARTTLS.
- Save and swipe down to fetch your mail.
Thunderbird
- In Thunderbird pick Account Actions, then Add Mail Account.
- Type your name, telenet.be address and password, then Continue.
- Wait for detection, then make sure IMAP with SSL is picked.
- If detection fails, type imap.telenet.be and smtp.telenet.be in yourself.
- Hit Done and the folders fill in on the first sync.
Telenet Webmail Settings#
Server settings connect your apps. These controls decide how the mailbox behaves on the server. They live in Telenet Webmail at webmail.telenet.be.
Signature
Add one in the Telenet Webmail preferences. Each address can also carry its own display name. A desktop app keeps its own signature.
Vacation Auto Reply
Turn on a holiday reply in Telenet Webmail. The server sends it, so it goes out even when your computer is off.
Filters and Folders
Build rules in Telenet Webmail. A server side rule sorts a message before any device downloads it. An in app rule only runs while that app is open.
Spam and Blocked Senders
Telenet screens incoming mail for spam. Block unwanted senders in Telenet Webmail. Flagged mail lands in the junk folder for a look.
POP3 vs IMAP#
| Feature | IMAP | POP3 |
|---|---|---|
| Where mail lives | On the Telenet 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 |
Telenet Mailbox and Sending Details#
A few details are worth knowing before you set up an app or add an alias. Here is how a Telenet mailbox is arranged:
| Setup protocol | IMAP or POP3 |
| Login name | Full telenet.be address |
| Incoming host | imap.telenet.be |
| Outgoing host | smtp.telenet.be on 587 |
| Mailbox size | 5 GB |
| Addresses per mailbox | Up to 5 (1 main plus 4 aliases) |
Troubleshooting Telenet 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 your full telenet.be address with your Telenet mailbox password. A bare mailbox name is turned down. |
| Cannot send on port 25 | ISP blocks the default SMTP port | Switch outgoing to smtp.telenet.be on 587 with STARTTLS and a login. Port 465 with SSL is the alternate. |
| An alias will not sign in on its own | Aliases share the mailbox login | Sign in with the mailbox password, the same one for the main address. Every alias uses that one password. |
| Family members see each other mail | One mailbox holds several addresses | That is the shared mailbox. For separate inboxes, give each person their own Telenet mailbox instead of an alias. |
| 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. |
| Mail goes out from the wrong address | The app uses the default identity | Add each alias as an identity in the app, then pick the From address per message. On a reply the alias the mail came to is chosen. |
| Cannot change the primary address in webmail | The primary account is fixed | Telenet keeps the primary address fixed. Set a display name on each alias. A mail app lets you send from a chosen alias. |
Reader Reported Fixes
Turn on outgoing authentication. If sending fails, switch on the outgoing server login and choose secure password verification. Telenet refuses unauthenticated sending.
Test the login in webmail first. Sign in at webmail.telenet.be with your address and password. If webmail opens, the credentials are right and the issue is in the app settings.
Sending As a Specific Alias #
The mailbox model decides where mail arrives. It also decides which of your addresses shows as the sender. Every telenet.be alias on the mailbox can send, not only the main address.
In Telenet Webmail each address, main or alias, can carry its own display name. That is the name a recipient sees on your mail, such as your first name or your full name. The primary address of the mailbox cannot be swapped in webmail, so the display name is how you shape what shows.
In a mail app you go further. Add each alias as its own identity, all with the same telenet.be login and smtp.telenet.be. Then pick the From address per message. On a reply, the app picks the alias the mail arrived on. Sending works because every alias shares the one authenticated mailbox.
| Item | What to know |
|---|---|
| What sends | Any telenet.be alias on the mailbox |
| Display name | Set per address in Telenet Webmail |
| Primary address | Cannot be changed in webmail |
| In a mail app | Add each alias as an identity |
| Login for all | The one mailbox address and password |
| Not supported | A non-telenet.be address through smtp.telenet.be |
Moving Mail In or Out?#
Telenet mail speaks plain IMAP, so a mailbox moves in or out like any standard account. Each folder stays on the server until the copy 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 imap.telenet.be with your telenet.be address and 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 Telenet 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 Telenet from the source list. If Telenet is not listed, pick a plain IMAP account.
- 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.telenet.be on port 993 with SSL. 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 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).
Telenet Mailbox Password
The one password for your Telenet mailbox. It opens Telenet Webmail and your email apps. It works for the main address and every alias on the mailbox.
imap.telenet.be
Telenet incoming mail host. Your IMAP client fetches mail from imap.telenet.be on 993 over SSL. POP3 uses pop.telenet.be on 995.
smtp.telenet.be
Telenet outgoing mail host. Sending goes through smtp.telenet.be on 587 with STARTTLS and an authenticated login. Port 465 with SSL is the alternate.
Telenet Alias
An extra telenet.be address that delivers into the same mailbox. A mailbox can have one main address plus four aliases, all equal.
Telenet Mailbox
The store that holds your mail on the Telenet server. One mailbox can carry up to five addresses. It is capped at 5 GB.
Telenet Webmail
The Telenet mailbox in a browser, at webmail.telenet.be. Sign in with your full telenet.be address and your mailbox password.
Secure Password Verification
The login method Telenet asks apps to use on incoming and outgoing. It sends your password over an encrypted channel rather than in the clear.
Main Address
The first telenet.be address on a mailbox. Aliases added later are equal to it, so any of them can receive mail in the same inbox.
Display Name
The name a recipient sees on your mail, set per address in Telenet Webmail. Your main address and each alias can carry a different one.
Identity
A sender address you add in a mail app. Set each telenet.be alias as an identity to send from it, all under the one mailbox login.
Send-As
Choosing which of your addresses appears as the sender. Every telenet.be alias can send through smtp.telenet.be, since they share the mailbox login.
How We Verify These Settings#
Univik builds email backup, migration and converter software since 2013. Our tools sign in to Telenet 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 Telenet klantenservice pages 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 Telenet 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
Telenet mail uses imap.telenet.be on 993 for IMAP or pop.telenet.be on 995 for POP3, each over SSL. Sending is smtp.telenet.be on 587 with STARTTLS and authentication. Sign in with your full telenet.be address and your Telenet mailbox password. The IMAP settings section holds the full table.
Check the username first. It must be the complete address rather than the part before the at sign. Use your full telenet.be address as the username and your Telenet mailbox password. The same password works for the main address and every alias, so there is no separate app password.
Telenet recommends IMAP. Mail stays on the server so every device matches. POP3 downloads it to one device and can lose it if that device fails. IMAP uses imap.telenet.be on 993 and POP3 uses pop.telenet.be on 995. Full comparison here.
Yes. The server, ports and encryption match on iPhone, Android and Windows. Only the path to the settings screen shifts by app, which the client setup guides spell out.
No. A Telenet mailbox holds one main address plus four aliases. They all share the one mailbox password. Mail for any of them arrives in the same inbox, so you set up the mailbox once and every alias comes with it.
Yes. Keep SSL on incoming and STARTTLS on outgoing so your sign in never travels in the open. Choose secure password verification, which Telenet asks apps to 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 Telenet mailbox. If you already exported files in another format, an email converter changes them to PST, PDF or whatever your new app opens.
The usual cause is outgoing authentication. Turn on the outgoing server login and pick secure password verification, then send on smtp.telenet.be over 587. If an alias will not sign in, use the mailbox password, since every alias shares it.
A migration tool copies mail across the two accounts on an IMAP link. Give the Telenet IMAP settings with your mailbox password on this side and the destination details on the other. Each folder lands with its dates 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.
Yes. Every telenet.be alias on your mailbox can send, not only the main address. In Telenet Webmail give each address its own display name, the name recipients see. To choose the sender in a mail app, add each alias as an identity under the same mailbox login and smtp.telenet.be, then pick the From address per message. Sending a non-telenet.be address through smtp.telenet.be is not supported. The section above walks through it.
