To repel spam mails and such with viruses, the university computing centre uses effective e-mail filters. Those are Sophos Pure Message systems, which are being updated several times per day. This ensures a high detectation rate.
A small amount of spam e-mails could still possibly get into your mailbox. In case you would like to report such mails, just send an e-mail to “email@example.com” with the spam e-mail attached to it. You can read the description of the process in the Sophos Knowledge Base: https://community.sophos.com/kb/en-us/23113
Spam e-mails that have been detected, are being held back by the Pure Message Gateway in the quarantine area. For informational purposes, you will receive one “Digest Message” e-mail daily. In case you would like to read a detected and filtered e-mail, please click onto the link within the e-mail. Alternatively, you can use the web interface under https://mx1.hs-woe.de/.
