That is the point, firewalls proxies and the like level the problem a bit, but
you still have to figure out, which stupid things your users are up to at the
moment and trying to work around that usually costs time, not to mention
risking system instability/obscurity.

So we put them on the servers and urge management to spill out same extra
bucks for some HW upgrade, right ;-)?

Actually I think, that this is the way of doing this. A few, sane corporate
rules with do's and dont's would imho remove much workload of the admin, as
s/he won't have to work around problems born out of stupidity (or better
said: uneducatedness).

AFAIK AV software is nowadays cabable of autoupdates.

This is an interesting point by the way, and one that should instantly ban M$
Outlook from each and every client. The AV Software is only needed, because
ppl are using a broken by design system, undoing with this (does one really
have to use outlook, if the only requirement is to sent/receive mail?).
Thinking a bit more about it, two questions remain nevertheless:
a) If no one uses outlook, would I need an AV soft license for my server?
b) Is email really the only way to catch malware? Thinking about Dialer spams
(the ones, only containing links to the real d/l) or diskettes...
... Personally I strongly believe, that each and everyone using a M$ system
should also have some AV soft installed for his/her own safety.

Bingo. Right now, I really consider, if it would be usefull to initialize
every newly created emailaccount in my mailsystem with a short tutorial of
do's and don'ts.

Oh, I don't think they are a bad idea ;-). I just think they should be
installed where the problem is.

To be honest, sometimes I wouldn't mind, if more malware was distributed.
Pain can have a tremendous learning effect ;->
