We are looking to at the possibility of sending out small email blasts inviting recipients, who have already opted into our customers email lists, to view pURLs (personalized URLs) generated by my system. We are going to be sending them out via an SMTP connection to my Exchange 2003 box from an application called XMPie.
For obvious reasons, I am concerned about my system being blacklisted for spam and am hoping someone can help me get to the bottom of a small debate. Do the DNS reverse lookups (PTR records) point back to my Exchange IP thereby putting my system at risk? Or, would I be able to temporarily redirect our customers domain name to my network (DNS) and have the to their domain name?
I would appreciate other opinions but documentation I can present to the powers that be would be even better.
