Configure User specific Filters for MPE's Mail Services

Each user has the opportunity to preprocess his incoming mail stream by a filter. Usual applications are:

• storing or dropping tagged Spam messages depending on the score
• putting mails from certain senders or with special subjects in different folders as inbox

Calling the Filter Editor

Login to [https://mail.mpe.mpg.de/tpl MPE mail user interface https://mail.mpe.mpg.de/tpl] and choose menu 'Edit Filter'

• when clicking the 'save' button a syntax check is performed. If no errors where found, the new filter rules are installed
• use the 'default' button to reload the MPE default filter setup
• use the 'back' button to go back to the main menu

the standard filter as a example

The standard filter contents is copied automatically to a new user's environment. Take this contents as a template to construct your personal filter. Feel free to comment or uncomment the following lines in order to enable/disable functionalities.

#Exim filterBR #BR #if $header_from: contains "myimportantfromaddress" thenBR #save /home/virtual_mail/$local_part/BR #finishBR #endifBR

#if $h_x-spam-level: begins "********" thenBR #seen finishBR #endifBR #BR

if $h_x-spam-level: begins "****" then BR save /home/virtual_mail/$local_part/.Spam/BR endifBR #BR

#if $h_from: contains "virusalert@rzg.mpg.de" thenBR #seen finishBR #endifBR

Please note that the first line has to begin with a '#Exim filter' line. The filter is executed sequential from up to down.

• 1 the first commented block allows to tunnel certain from-addresses direct to your inbox without scanning for spams

  2 the second commented block allows to drop Spams with a certain level

  3 the third active block stores all spams from 4 * and more in special Folder 'Spam'

  4 the forth commented block allows to drop Mails with a certain from-Address
