Just for your information:

In cases like this, I found a site helpful, which contains many
blackhole-lists. You may check, wether your mailserver is
blocked by these anti-spam-lists by using the following link

http://relays.osirusoft.com/cgi-bin/rbcheck.cgi

If the server is using several IPs (as is often the case
when you run an internet server hosting several virtual
domains and such stuff), it's good to check the whole
IP-range used - depending on how you set up your smtp-server.

The site also has links where one can get information
about how to secure the different mailservers in use
(sendmail, postfix etc.).

HTH
Michael
