Amavisd-new is an interface between MTAs and content checkers. Content-checkers scan email for viruses and/or spam. Amavisd-new is written in Perl and runs as a daemon. Instead of accessing SpamAssassin via the spamc
or spamassassin
clients, it loads SpamAssassin into memory and accesses the SpamAssassin functions directly. It is therefore closely coupled to SpamAssassin, and may need to be upgraded at the same time as SpamAssassin.
Amavisd-new is available in source form, RPMs are available for SuSE and Mandrake Linux, and third-party RPMs are available for RedHat Linux. Details of versions available are listed on http://www.ijs.si/software/amavisd/#download. If an RPM is available, use it.
