MX/txt record confusion
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? ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja~

It should - we do it all the time with a half dozen domains - unfortunately I'm not the exchange guy so I may not have answers on what else may need to be done.

Re: MX/txt record confusion
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.

Re: MX/txt record confusion
An employee who uses an @secondarydomain. address sent a message to someone and their mail server did the reverse lookup and bounced the message. The smpt message says, mail.primarydomain.com #5.5.0 smtp;553 sorry, relaying denied from your location and then has to correct IP address listed at the end of that message. Only reason I can see for it to fail to lookup would be the inconsistency between her email address and the mx lookup or whatever resolved to mail.primarydomain.com and not mail.secondarydomain.com?? As you can see, I have only a very basic grasp of what may be going on here.

RE: MX/txt record confusion
If it's outbound, it sounds like PTR or SPF issues. Although I've heard that there are some domains that expect sending SMTP servers to have MX records whether or not they accept inbound mail - sounds crazy to me.
