Settings for e-mail clients

If you want to retrieve your e-mails with a program for which no detailed instructions are available on our websites, you can find an overview of the necessary settings here.

  • Incoming (Server for Incoming E-Mails)

    In order to fetch your e-mails with an e-mail client, you can choose between two access methods. We recommend to use the "Internet Mail Access Protocol (IMAP)". It enables you to freely move your messages between your inbox, folders on the central server and folders on your own PC. The older "Post Office Protocol (POP)" only allows downloading incoming e-mails to your own PC and is therefore not recommended.

    IMAP (recommended)

    • Server name:
    • Port number*: 993
    • SSL/TLS encryption*: Activate
    • Login name: Your university ID
    • Password: Your university password
    • Advanced settings (IMAP server directory / master folder path)*: Mail
    • Advanced settings*: Display all folders, whether suscribed or not
    • Advanced settings*: Folders can either contain subfolders or e-mails


    • Server name:
    • Port number*: 995
    • SSL/TLS encryption*: Activate
    • Login name: Your university ID
    • Password: Your university password
    • Advanced settings*: Delete e-mails directly after they have been fetched

    *With many e-mail clients, these settings cannot be made when using the wizard for adding a new account, but must be made later in the account settings.

    (Note: When using POP, do not configure your e-mail client to leave a copy of messages on the server. You risk deleting wrong or even unread e-mails. This is a fundamental problem of the POP3 protocol.)

  • Outgoing (server for outgoing e-mails)

    In order to send e-mails, you have to use our  SMTP server "secmail".It can be accessed both from the university network and worldwide. If a client (e.g. of a measuring device) cannot be configured to use secmail because it does not support authorization or encryption, please contact our Hotline.


    • Server name:
    • Port number*: 587
    • TLS encryption: activate/STARTTLS
    • Login name: Your WWU ID
    • Password: Your WWU password
    • Advanced settings: Server requires authentication

    *Many Internet service providers block connections to port number 25, so you should use port number 587. Users of Outlook 2003 or older are excluded: You can only activate TLS encryption by enabling SSL encryption and using port 25.

    (Note: T-Online clients using Speedport routers have to add "" to the list of safe SMTP servers in their router.)
