The main mailservers at Uppsala University are taken care of by IT-division. The main spamfilter is taken care of by SUNET.
Please note that the anti-spam filter will put mail that has been classified as mail into the Skräppost / Junkmail folder automatically. Please check there if you are missing mail!
To troubleshoot mail you are missing you need the following information:
- Sender of mail
- Receiver of mail
- Date and time
Send the request to the postmasters at Uppsala University who can be reached at firstname.lastname@example.org.
If you have recieved the mail but still have questions where it was kept up you can open the mail headers and look at the ones beginning with received:. A mail only sent internally in the Exchange server at the university does not contain any such lines.
This can be found in Thunderbird by pressing CTRL-U. For Outlook 2013/2016: Open the message in its own window, On the File tab, select Properties and the header information should appear in the Internet headers box.
In the example below it looks like the mail was delayed 17 minutes in e-mailfilter04.sunet.se but it does not explain the reason - could the next receiver lyra.its.uu.se not receive the mail at that moment or were there queues internally in the e-mailfilter04.sunet.se? To investigate such things further the postmasters have to look at for example queue lengths or other logs for the mail servers.
