amavisd-new =========== http://www.ijs.si/software/amavisd/ amavisd-new is an interface between message transfer agent (MTA) and one or more content checkers: virus scanners, and/or SpamAssasin ( http://www.spamassassin.org/ ). amavisd-new is a performance-enhanced and feature-enriched version of amavisd (which in turn is a daemonized version of AMaViS or amavis-perl). It is normally positioned at or near a central mailer, not necessarily where user's mailboxes and final delivery takes place. If you are looking for a per-user and low-message-rate solution to be placed at the final stage of mail delivery (e.g. called from procmail), there may be other solutions more appropriate for your needs. amavisd-new benefits from the use of Perl module Net::Server, which offers a fast pre-forked multichild environment. Several new features are offered, including SMTP-in/SMTP-out capability. This makes it suitable for mail anti-virus and/or anti-spam checking on a busy mail gateways. All the modifications since the original amavisd done by Mark Martinec, with contribution of ideas, reports and patches from amavis-user mailing list community. See RELEASE_NOTES, INSTALL, and files in the README_FILES/* subdirectory, at least the one pertaining to your MTA (Postfix, Sendmail/milter, Exim). If running a dual-MTA setup (any MTA type), the files README.postfix, README.sendmail-dual and README.exim_v4 describe a similar setup and can be used as guidelines. The two programs in the subdirectory helper-progs/ are only needed for interfacing with sendmail (with milter or in the old setup, but not for the README.sendmail-dual setup), or with older Exim (v3). Helper programs are not needed if using Postfix or Exim v4 or dual-MTA setup.
