It can be set up on your gateway, integrates with exim very well, and can virus scan as well as spam scan. www.mailscanner.info and for howtos http://wiki.mailscanner.info/doku.php?id=&idx=documentation:configuration:mta:exim -------------- next part -------------- A non-text attachment was scrubbed...
