Here's a few good reasons why an ISP might have server filtering
of some kind:
1. Viruses cost us money in terms of support calls
("Hi, my Internet doesn't work").
2. Spam filtering keeps customers, and doesn't have the
administrative costs of them changing their e-mail address every
once in a while
3. All of us ISP employees are sick of receiving viruses from
customers (happens to me on a daily basis -- haven't gotten all
the filtering 100% implemented yet), and if we're doing it for
ourselves, we might as well do it for the customers.
4. For outgoing mail, to save on bandwidth costs
