For many of us, the constant stream of Microsoft outlook viruses is
just an annoyance rather than a threat, but it is a big annoyance none
the less. I find the following in the header_checks of my postfix
configuration nicely kills all such garbage before it hits me:

/^Content-(Type|Disposition):.*(file)?name=.*\.(asd|bat|chm|cmd|com|dll|exe|hlp|hta|js|jse|lnk|ocx|pif|scr|shb|shm|shs|vb|vbe|vbs|vbx|vxd|wsf|wsh)/     REJECT Sorry, we do not accept .${3} file types.

It works with any postfix past the 2.0 release, and works very nicely.
