Can someone please tell me how to patch my Linux box? It is having trouble executing this virus attachments...

More seriously -- Not only are "Automatic virus replies considered harmful..." they actually double the internet damage a worm can cause. I dred the day I see a worm-found auto-mailer challenge an Out-of-Office response bot to the death.

Which brings me to "Out of Office response bots considered annoying"...

At the risk of being totally off-topic, but hey, there must be more than one sysadmin in the audience using Postfix as an MTA...

I have a regex that looks for antivirus spew in order to reject it. Someone had collected a large list of subject headers received from antivirus malware and posted it to the Postfix mailing list. Rather than bog down my server with a check against each subject, I used Perl to build one regex to match them all (and in the darkness bind them :)

If your postfix installation was compiled with the pcre library, you can use the following:

Note: the above is senstitive to spaces. Make sure you "download code" rather than a simple cut'n'paste.

I've put the RE in a <readmore>, something I never do as a rule in a reply, but it occurs to me that if for people who have long line code wrapping turned off it will make the page rather... wide.

In any case, it's been weeks since we have been bothered by the antics of antivirus software.

Man, you should have used the /x switch, grinder! </troll> </lame-slashdot-emulation>

Can someone please tell me how to patch my Linux box?

Trivial. Every MTA worth its salt, and that includes most available for Linux, knows how to deal with a .mailcap file. Even browsers like Netscape know how to deal with a .mailcap file. It's very easy to configure your .mailcap file so it fires up perl whenever you receive an email or webpage with MIME type application/perl. Or fire up another turing complete language interpreter for another MIME type. Does your mailer conveniently fire up a PostScript viewer when you open up a PostScript attachment? PostScript is a powerful language, are you sure your PostScript interpreter doesn't have security holes?

Thanks -- I am almost set up now. My only hope now lies with Mono (ugh, now there is a disease for you) and VB.NET so I can run the more modern viruses.
