To complete this discussion, recent sieve standards/proposals have support for a generic interface to external spam and virus filters such as spamassassin, called at sieve runtime (i.e. not decisions based on earlier added headers), see [1]. Pigeonhole sieve for Dovecot [2] supports this. pigoenhole also has experimental support calling arbitrary external programs in an administrator-controlled way [3], which I use with great success to add spamtrap messages to a database. I hope this might convince people to try sieve once more as a replacement for procmail ;) [1] http://tools.ietf.org/html/rfc5235 [2] http://pigeonhole.dovecot.org/ [3] http://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/Extprograms -- Regards, Tom
