Since you mentioned procmail, my buest guess is that your Postfix/Zarafa integration is similar to the wiki page at http://zarafa.com/wiki/index.php/MTA_integration This leaves me slightly puzzled, because I can't imagine where you'd want to plug in a Sieve filter: The setup describe above looks like the program "zarafa-agent" is doing the final delivery (as far as Postfix is concerned), which means that ultimately, the decisions on things like the destination mailbox are made by Zarafa, and not any intermediate MDA (mail delivery agent). What excatly are you trying to do with Sieve filtering? Cheers Stefan
