Hi Michael, Why would i need a remarkworldwide.com MX record? i am not sure...our domain name is remarkgroup.com, all our email address have a @ remarkgroup.com format.
What happened is that our smtp smart host external IP has a PTR record that was set to mail.remarkworlwide.com by the previous System Administrator, this was set up like this so reverse-dns lookups would work (as antispam engines do reverse lookups). Would that make sense to change the PTR record from mail.remarkworldwide.comto mail.remarkgroup.com ?? On Tue, Jun 26, 2012 at 2:00 PM, Michael B.
