Sieve Filtering

THIS IS NOT AVAILABLE YET.

What is Sieve filtering?

At a basic level, Sieve is a system whereby the server is given rules be you to filter your email in to folders. It then means, that whatever email program you use, your email is already filed away in to it's correct folder according to your needs. Sieve can do more than just move email to their correct folder though.

Creating Sieve Filters

Our IMAP servers run 'ManageSieve', this is a service which clients talk to in order to create and edit sieve filters. ManageSieve runs on port 4910, and there are various clients which support ManageSieve, eg:

• RoundCube - our webmail has a Filters option in the settings
• Extension for Thunderbird (not that great)

Whatever IMAP email program you use the Sieve filtering will still work. It may be easiest to create and edit the filters using Roundcube webmail even if you don't wish to use Roundcube for reading email.

4. Go to Tools - Sieve Message Filters
   1. Click 'New...'
   2. give it a name, eg My Filters
   3. Paste in the results from the converter page
   4. Check that there are not any errors reported, then click Save.
   5. Close the tab with the script, and you'll be returned to the SieveFilters tab
   6. Clickt he little Active button so that it turns in to a green tick.
   7. Close that tab
