I am having a problem:
I have multiple virtual mail servers behind a pfsense firewall. Now on each server, I have multiple domains. Now sending to the domain from google or yahoo is perfect and out again is perfect but when I send a message from one virtual server to another which is hosting the destination domain, it errors out. Now when I telnet the public IP that the 1st virtual is assigned, it just sits there and times out. This is making it impossible to send messages from domain to domain within the network. Any ideas?
