Spreadsheets, mostly. there is the ocasional pr0n video. I have a 6Mb per
message maximum on sendmail.

It's no calling a virus scanner. it calls spamassassin, but acording to
mimedang-filter, it doesn't call spamassassin if the msg is bigger than
100k. I'll coment SA lines out in mimedefang-filter and see if that helps.

I'm not absolutly, 100% sure it's MD. there are a lot of perl processes
eating a lot of memory, and that memory gets freed as soon as I shut MD
