I'm not sure exactly how these things happens, but I've gotten lots
of virus mails without the payloads attached. Sobigs, Mydooms, all
sorts of things. I get alot of crap mail. :-)
One theory is that the viruses are buggy.
Another is that the payloads are getting stripped by stupid mail
filters, without any notices or warnings getting attached. This
could easily happen in a company which automatically enforces a "no
outgoing attachments at all" policy.
This could also be caused in obscure cases where a machine has
partial A/V protection - not enough to keep the infection from taking
place in the forst place, but enought to keep the "build a new
infected mail" process from succeeding.

That's remotely possible of course, there are always new bugs to find and
squash. :-) But I've seen so many of these which haven't been touched by
Anomy that I don't think it's the most likely explanation.
