OpenBSD Kills E-Mail Viruses Using smtp-vilter

Contributed by jose on from the killin-the-baddies dept.

Marc Balmer writes: "We have been using OpenBSD, sendmail, Clam Antivirus and our own smtp-vilter, a high performance content filter using the milter API, for months now. This combination makes a rock solid mailgateway with full virus protection.

smtp-vilter is the interface between sendmail and the actual virus scanner an can be configured for different backends. It has been developed, tested and used on OpenBSD (and runs on Linux as well.)

Today we released smtp-vilter under the BSD license. The software can be downloaded at http://www.etc.msys.ch/software/smtp-vilter . A port to ease installation is on the way..."

That's pretty awesome. Not only do you get a secure, high performance mail server that's resistant to the typical Windows desktop viruses and worms, you get to do it on a budget. Thanks, Marc!

        This product is great, especialy if you have different types of users. Like i know some folks communicate a lot with msn/hotmail/yahoo whould think i'm a bid rude when i block jp,kr,sg,tw,biz,hotmail*,msn*,yaho,*money* etc. The few people i do know using those spam magnets are white listed.
        In short every user can be hold responsible for his own config besides the 'main' config offcourse & keep an eye on there own quarantine.

    It seems to me the word "secure" gets thrown around a lot. I'm curious how anyone can claim some software is secure that was only release publicly today. I get that it isn't windows, but that's pretty much a given around here. Yeah I know, this is just a minor nit. Or perhaps there is some good info I didn't see?

      Perhaps "secure" was referring to sendmail on OpenBSD. Only time will tell if this new link (smtp-vilter) won't weaken the chain, of course.

    How does it compare to the MILTER already part of CLAMAV?

      I acually have the same question....

      I am trying to sort this out right now. Maybe somebody can come up with good answers in this area.

      I have seen the following:
      * smtp-vilter (stand alone)
      * clamav-milter (built in)
      * IVS-Milter (stand alone)

      Is there a reason for not using the built in clamav-milter in clamav (except that smtp-vilter can use the Symantec engine) ?

      How about the future for these three mentioned above ?

      But smtp-vilter looks nice and compiles ok on my OpenBSD 3.4 box without any trouble...
