Error message "The incoming mail server is already in use"

If you have already created a mail account in Thunderbird with the default mail address benutzername@(smail.)uni-koeln.de, you cannot set up another mail account with your alias address in the way described above. This applies to all types of alias addresses, i.e.

  • vorname.nachname@uni-koeln.de or v.nachname@uni-koeln.de for personal accounts
  • bezeichnung@einrichtung.uni-koeln.de for aliases in virtual mail domains
  • vorname.nachname@smail.uni-koeln.de or v.nachname@smail.uni-koeln.de for student accounts

In this case, you will receive the message The incoming mail server is already in use when you try to set up the mail account.

This is because the alias address is only a reference to the existing e-mail account, but not an independent e-mail account that you could query separately. All e-mail messages, regardless of whether they are sent to the standard e-mail address or to the alias address, end up in the same inbox folder.
