Hi Gurus, We have our primary DNS , webserver, email server everything inside firewall, all natted to WAN IP. Hence our mails are having the originating IP as firewall's IP ad hence some domains are rejecting our mails. The webserver and email servers IP are same since they both are on the same machine. can anybody please guide me what rules I am doing mistake in firewall and how this problem can be solved.
