Email & Calendar
At WU multiple email systems are used simultaneously. Using the Controlpanel, you can identify in which email system your mailbox is integrated in. To ensure safe email correspondence, please note our IT security policy.
Please also mind our IT security recommendations and be careful when opening emails and attachments from unknown senders.
To protect computers from spam and malware, restrictive rules for WU email addresses were set up. More information on this topic is provided in the "Directive on the Rejection of Emails with Objectionable Content" - the contents are summarized in the boxes below.
Central SPAM Filter
The central spam filter at WU checks all incoming and outgoing emails for viruses and spam. Emails identified as spam, are rejected. The sender is usually notified about that.
Changing Spam Filter Settings
The Controlpanel application allows you to adjust your spam filter settings.
Select: My email > Spam filter.
Anti-SPAM Block Lists
Greylisiting – Delayed Delivery of Emails
Incoming emails from unknown mail servers or senders are delayed by greylisting, i.e. emails are only accepted after a certain period of time. So the majority of potential spam is filtered out as senders of spam mails will usually not try sending it again. However, a disadvantage of this method is that non-junk mails are sometimes delivered with some delay.
List of Blocked Attachments
Mail servers operated by IT-SERVICES currently block the following data types for email attachments (case insensitive):
zip (with restrictions)
Mailing Lists and Distribution Lists
In addition to your own mailbox at WU, mailing lists are used to communicate information effectively. WU employees can find further information on mailing lists on the intranet.
Frequently Asked Questions
For whom can a mailbox be set up?
WU employees and WU students automatically receive a mailbox. Third-party funded employees and student employees receive one only after the approval by the responsible Vice-Rector.
Do I have Aliases at WU?
You can check your aliases in the Controlpanel application.
Select > My email > Email info.
May I set up email forwarding?
Email forwarding is only provided for students. As regards WU employees, forwarding to external email addresses are deactivated for safety reasons (data privacy).
Why are emails delivered after a delay?
Apart from greylisting (see above), there might also be other problems with delivery - e.g. if the email was not sent by the originating server. It might also be the case that the sender is on a black list. In this case, the person concerned must try to eliminate their IP addresses from the black list.
