That won't fix PTR issues if the IP's are owned by the ISP, they are authoritative for the records on the IP address space.

McSpadden [mailto:dav...@imcu.com] Sent: Tuesday, November 17, 2009 8:51 AM To: NT System Admin Issues Subject: Not wanting to be a spammer I have an email mailer I am supposed to send out. It is going to 12000 customers that have asked to be notified by email. I got that script late last week and I have it set up to run from my machine, relay off my exchange server, through my Ironport, and out my firewall. I do not host the mail at imcu.com and that is the address space I want to sent it from. In testing yesterday it seems that everyone will flag me as a spammer because the email source can not be reverse looked up properly. Now I do own a second domain. imcu.org and I do have an MX record that points to my firewall. This seems to be the better way to do it. Have it come from x...@imcu.org<mailto:x...@imcu.org> but have a reply to of x...@imcu.com<mailto:x...@imcu.com>. I do host the imcu.org mail server internally so I could just relay off that smtp server through the ironport and out the firewall with little or no worries of getting blacklisted. Right??? Am I even close to thinking this through correctly?? ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
