I've had some luck with various tools on Postfix, I found it far easier than with Sendmail. Anyone have any good tools they like?

    avcheck is a really simple and well-working interface to the Kaspersky or DrWeb virus-scanner.

    i'm using amavisd-new which integrates SpamAssassin and many antivirus tools - ClamAV works fine for me. amavisd-new works perfectly with Postfix in many diffrent possible ways to set them up.

    also there is a nice OpenBSD-related howto available:

      A very nice page.

    If you are looking for a commercial solution I can recommend Central Command Vexira MailArmor - they have a supported OpenBSD version which can run as a Postfix content filter. I have been using this on a production site for over 6 months and have been very happy - see

    If you are looking for a free solution try ClamAV

    i have had good success wit the Anomy Mailtool ( While not exactly an antivirus, it does make sure that no dangarous files get through. see more here to find a howto for setting it up along with spamassassin.

    inflex - open source -

    xamime - commercial (same developer) -

    Ive have used both, great software. Works with sendmail and postfix. Others are in the works.

    I've been using RAV with sendmail w/milter support for quite some time now. RAV is commercial, but it has been rock solid. It'll work just fine with Postfix as well, but we've noticed quite a bit of a performance boost by using milter.

    Is there anything relating to Norton perhaps under Linux emulation, or planned with Norton in the future? Out of habit, I trust it under Windows and I like it's auto update technology on Unix servers.

      Well i use RAV + postfix under OpenBSD and I was very satisfied. Has autoupdate too, but this product was buy by Microsoft and they announce that will stop development under Unix,Linux and Novell...

    I have postfix+amavisd-new+spamassassin+f-prot
    This setup works for me with 4 postfix style virtual hosts.
    It's all free and it survived the upgrade from OBSD 3.2 to 3.3-CURRENT.

    If someone's interested mail me and I can send you my config files.

    1. By Anonymous Coward () on

      F-Prot is a great scanner and works well on OpenBSD, but it's not free for commercial use.

      amavisd-new with Postfix works well, but if you've got time to play, give Exim with the exiscan-acl patches a try, it's just *so* nice to reject spam and viruses right at the SMTP port...

    We used to use SpamAssassin and Amavis (on Sendmail) for this kind of thing, until we noticed that some mails were taking upwards of 20 seconds to process. We moved to MIMEDefang ( which , and we haven't had any performance issues since then.

    a combination of
    and clamav + spamassassin
    works for me

    (and spamd ... the openbsd, not spamassassin one)

  11. By Anonymous Coward () on

    they have openbsd versions which are free for personal use by registering, have been meaning to try it but never got around to it...

    just wondering, has anyone ran it?

    1. By G () on

      Works fine, but has disfunc LKM included

  12. By KrUsTy! () on

    Here's Great how-to for adding spamassassin and spam control in postfix (for openbsd too).

  13. By Soup4you2 () on

    I've been using Amavis-new for postfix and using sophis and clamscan and seems to work great..

    definatly worth setting up.. not hard either..

  14. By Jankok () on

    Postfix + Virge + Sophie. Rock solid, fast and
    very nice on system resources.

  15. By Scott () on

    A great package for postfix that includes antivirus, spamassassin.
