This is an old revision of the document!
Every incoming e-mail is filtered by some e-mail filter rules, based on a language called Sieve.
E-mail filters rules include: vacation, forward, spam filters, general filter rules. These 4 points (your main filter settings included) can be managed using the web interface of Horde or SquirrelMail ONLY. The old one, based on Procmail, is now disabled.
All e-mail clients (pine, thunderbird, etc.) filter rules work after the rules managed through horde or squirrel, so any e-mail client can not overwrite or overtake the rules fixed/managed through webmail service
But remember that the settings defined using horde are not exportable to squirrel and viceversa.
If you define a rule, this will be active until when you change or overwrite it. The activated filters are the ones which have been saved for last.
This means for example that:
- setting/modifying a configuration (filters too) using squirrel will overwrite horde rules and viceversa. So manage your configuration using always horde or always squirrel. For example: you have NOT to set forward and vacation with horde and then spam filter settings with squirrel… or viceversa.
- but your can read/send/manage your e-mails using squirrel, and use the filter settings set through horde without any problem.
To avoid any problem, to modify/enable/disable your e-mail filter rules use always the same webmail service. NOT BOTH!!
