We recently added our own server (SBS 2003 w/Exchange). Our domain registrar has added the correct mx record with rDNS entry,however, we are unable to send to aol or comcast and get the following response:
Could not deliver the message in the time limit specified. Please retry or contact your administrator.
WARNING: One or more of your mailservers is claiming to be a host other than what it really is (the SMTP greeting should be a 3-digit code, followed by a space or a dash, then the host name). If your mailserver sends out E-mail using this domain in its EHLO or HELO....
mail.hollychevrolet.com claims to be non-existent host hollychev.local:
220 hollychev.local Microsoft ESMTP MAIL Service, Version: 6.0.3790.3959 ready at Sat, 21 Jul 2007 09:31:25 -0500
I'm certain the issue has to do with mail.*.com and host *.local, but can't determine what changes I need to make.
