From ULYSSIS documentation

Your ulyssis account includes an email address: It is important you check your ulyssis mailbox regularly, because all important information will be sent to this address. You can check your e-mail using webmail or an email client of your own. It is also possible to configure your email address in UCC to automatically forward all correspondence to another address.


You can access your mail via a webinterface: Use your username and password to login.

POP and IMAP access

You can access your ulyssis mail with POP or IMAP. The configuration parameters are:

  • server:
  • port: 993
  • username: your ULYSSIS username
  • password: your ULYSSIS password
  • security: SSL


NoticeTo use your mailbox with an external application, access to the KU Leuven SMTP server is required

Since 24 February 2023, not all students have access to by default anymore. If you are unable to send emails after following the instructions outlined in our documentation, then you may have to register on to (re)gain SMTP access.

ULYSSIS doesn't offer SMTP. Instead, you can use KULeuven's SMTP server:

  • server:
  • port: 443
  • username: your student id
  • password: your KULeuven password
  • security: SSL


Your emails are stored within your account under ~/Maildir. These files can of course be read with a command line email client such as alpine or mutt.

We support sendmail style local delivery using .forward. More information is available in the official documentation of Sendmail and Postfix. While it's possible to use .forward to simply forward email to other addresses, we recommend only using it when the same feature is not available through our control panel UCC. Specifically, .forward can be used to pass emails to other applications. In the past, a popular application to pass email through was procmail. However, procmail has not seen development for about 2 decades, and its developer suggests not using it anymore. So while some users may find procmail filters useful, we do not support or suggest its use anymore. A detailed manual for procmail is available on the ArchWiki.
