So, from the outside, you tried to send an e-mail to your MX record for mail.primarydomain.com, and you got an "unable to relay" NDR (bounce) message? Was that address local to that MX record? If yes, you probably have a spam filter issue.
Note: TXT records are for specifying SPF or SenderID information. You are still missing PTR records. Does your mail server do the DNS ménage à trois? <http://www.espinola.net/blog/archives/5> On Jan 24, 2008 4:14 PM, Jeff Brown <[EMAIL PROTECTED]> wrote: > I have a secondary domain setup in my exchange environment, only a couple of > folks using that domain email. > > Got an ndr that says unable to relay for mail.primarydomain.com at x.x.x.x. > > I have setup mx, A and txt records for the secondary email domain, > mail.secondarydomain.com > > This was done with the help of a consultant who is an exchange specialist, > in whom I have a lot of confidence. > > That being said, I'm wondering if exchange ever really sends mail out using > mail.secondarydomain.com?? > > Can someone enlighten me please? > > -- ME2 ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
