I'm interesded in > MailScanner alternative for postfix - links, documentation, examples... i have postfix in use with amavis. works excellent. can on amavisd-new also configure spam-support with spamassassin. a little bit hard for the first configuration, but excellent. supports many archives - means unarc and check for viruses. written in perl. Download and documentation at http://www.amavis.org. look for amavisd-new, which is running in a separate daemon and can be used by postfix as content-filter. HTH Roger > > -- > Regards, > Doncho N.
