    A starting point would be to ensure that SpamAssassin does not forward emails that are flagged as spam, that can be a real problem and I think it is off by defult. In our bulk hosting, we use a product called MailChannels that filters all outbound email to ensure your server is not sending spam and prevents your server's IPs from getting blacklisted.
