Not sure how spam can lead to malware infestations (yet), although I'm
pretty sure the reverse could be true.
What version of Outlook do your clients use? OL2003 won't download HTML
images by default (you have to enable it per message when prompted, although
you can disable this feature...that isn't advisable). This will help defeat
'phone home' beacons which can lead to more spam.
Re traffic, well, of course your Exchange server has to devote resources to
accepting/processing/delivering or rejecting mail, so even undeliverable
spam will keep it busy sending out NDRs. Take a look at your queues & see
how many outbound msgs are showing up from your server itself... and check
your badmail folder (which should be purged daily anyway).
When you tell your managers you're using 'word filtering' (not sure what you
mean exactly; or what you're using to do it with, or how much valid mail you
might be blocking) and somehow seeing that that itself is handling 30% of
the spam, on top of what users actually receive, what do they say?
Do they want users to be spending their time going through spam? Do they
want delivered spam to take up space in the mail stores? Do they want your
server to be busy sending out NDRs? It's really up to them if they think thi
s is a problem....personally I know of very few companies who don't have a
problem with spam at all, and it's only a matter of time. If you have over
400 users, well, I'd want some antispam filtering before mail even hit the
Exchange server(s) and so would most people I know, but it's more of a
business decision, really.
