Update mail server filtering with sieve

Get the filter rules

Steps to update the sieve filter rules.

  • Logon to the server
  • Run sieveshell $ sieveshell --user=gill fairlane
  • List the rules currently in place: > list
  • Export the rule definition to a file: > get filter_from_list text_file.txt
    > quit
  • Edit the file (after quitting sieveshell): $ vi text_file
  • Import the definitions > put text_file filter_from_list
  • Activate the rules > activate filter1
  • Quit sieveshell
    Now you can try server-side filtering.
