Gee, I can't say that I consider myself a luminary... ;-)

Just FYI, there would be hundreds more of these every day on the mailing
lists too, if these lists were not moderated. Being the owner / moderator of
the Struts lists, I get to wade through them all and determine which
messages are valid.

The reason I bring this up is to encourage those of you who post relatively
frequently, without subscribing (you know who you are!), to please subscribe
to the lists. Doing so will result in your messages getting to the list much
more quickly, as well as reducing the number of messages I have to wade
through every day. ;-)

Unfortunately, inspecting headers doesn't tell you all that much, since
pretty much anything in the mail protocols can be spoofed. It can help you
weed out the dumb senders, but the proportion of those is falling.
Anti-virus isn't the whole answer either.

What organisations really need, to protect their email users, is a
comprehensive "email firewall" product that combines anti-spam, anti-virus,
and other protection schemes. The only such beast I'm aware of that really
works (and it does work awesomely well) is a product of a former employer of
mine. Unfortunately, it seems unlikely that Apache would deploy this
particular solution, due purely to OS biases.
