The MyDoom worm has made its presence felt here already. Last night we started blocking .zip files as a temporary measure until NAI could get a datfile out. We still got hit in many places, partially due to mail that got through before the ban, and partly due to folk who've set up their outlook to fetch their private mail from work. So far, things seem to be holding steady. The mailserver is keeping up with load. Our helpdesk doesn't seem too overworked. Even if our mail admin is Cran-key with a capital CRAN. People keep calling him. Not a good idea.
