I have been having a problem with being blacklisted for some reason. I am try to lock down my Edge exchange server to resolve the problem so I have install my McAfee client from my Sonicwall device but whenever the firewall is enable I cannot receive outside email. I have enable the following TCP ports but still not working. What am I missing?
53, 389, 143, 110, 25, 443, 445, 465, 80, 993-995, 3268-3269, 50386-50636
