Does the Math Department block mail from any domains?
Yes. We block mail in several ways. First, we have several groups of IP addresses (consisting of literally millions of IPs) that we simply drop connections from. These are known spam hosts on ISP networks that either can’t or won’t clean up their act. This list is updated daily. Next, we check each connection against three sets of databases of well-known spammers. We also check to see if the address is a dynamic IP. If there is a match, we reject that connection too. Finally, we scan incoming mail for virus content and discard any mail that contains it. We do not filter email based on content, except to look for viruses. Filtering email is an inexact science. It is possible (actually probable) that we are blocking some sets of addresses too aggressively. If someone is having difficulty getting mail through, please have them mail me (Zube@cs.colostate.edu) and provide details such as where they are trying to email from (what ISP they are using, the outgoing SMTP server, etc.), who they
