How can Exchange server behind the firewall get the internet email without configuring the port forwarding(not through POP3) in the firewall ?
Can anyone have idea about this? I setup Exchange 2010 and it can send/receive email within LAN (behind the firewall) . Getting internet email should be easier if we can setup port forwarding in the firewall. Now I have DNS name registered in Godaddy and I can also have access to internet, but I cannot have the access to the firewall to setup port forwarding. so, do you think I can have the Exchange server receive internet email without configuring the port forwarding? Thank you in advance.
