If mail coming from the systems you operate (IronPort) will always originate from IP address 206.18.123.221, that would be correct. If you have other hosts that might be sending mail directly, add them, too. (An Exchange server, for example. Maybe your IronPort goes down, so you reconfigure Exchange to send direct.) > A record mail.imcu.com 206.18.123.221 > > ptr record 221.123.18.206-in-addr-arpa mail.imcu.com That looks good. Now, SPF doesn't look at A and PTR records unless you tell it to, so they're not directly relevant for the immediate problem. However, it's considered a best practice to have A and PTR records for mail systems, and some spam systems take that into account, so it's a good idea to have them. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
