Are you positive that that is really what it's named when MS/Clamav
sees it? Might be zine alarm fiddling with the name...

About the virus name... What one AV calls a virus rarely map exactly
with what anyone else is calling it. For all we know, ZA night call
Sober.U (clamav) for Sober.W (compare with for example f-secure, that
call it Sober.Y ... still the same thing though). So that isn't much
of an indicator, unfortunately.
Are the archives really valid? Unpackable? If you unpack one of them,
and run Clamav on the unpacked content, is it detected then?

I see you run FreeBSD, but seem to only run clamav... Consider adding
BitDefender too, and see what that gives on the specific troublesome
mails (
Unless you already have it, but haven't told us about that:-).
