I dare say probably any of these can be combined with Mfilter which I'm probably the main developer of at the moment. Works with sendmail and Exim that we've tried so far but is probably easily adapted to others, worst case you can run your existing MTA on a different port and write something to direct the passed emails to it. You basically receive mail with Obtuse-smtpd listening on port 25, pass it through Mfilter which is basically a perl script (for the moment) that performs some check of your chosing (virus scan, custom script, file type blocking, sender/receiver based blocking) and decides whether the mail should continue or be trashed/archived. If it's passed it then gets forwarded (using smtpfwdd) to your regular MTA for onward delivery. Mailed messages optionally respond to the sender telling them their mail may have a virus for example (and includes the log - optionally). There's also a script that does nice pretty statistics and outputs HTML pages. Grab the latest version out of CVS off SourceForge, the current 'release' is truly ancient, the CVS one is stable enough and runs in a user context rather than as root. -- ---<GRiP>--- Web: www.arcadia.au.com/gripz Phone/fax: 02 4950 1194 Mobile: 0408 686 201 -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
