I can receive emails from other addresses with no problems, but 2 different people with yahoo accounts had this issue. Both on iphones.

Is this a problem on my end or theirs?

Thanks.

To: example@yahoo.com

Subject: Failure Notice

Sorry, we were unable to deliver your message to the following address.

The problem is at the example.com domain. Can you post the raw message or the mail headers? – Carl Abrahamsson Jun 28 '13 at 19:50
    
Sure, the message was forwarded twice, care to tell me exactly what you're looking for, and I'll post it? – riseagainst Jun 28 '13 at 19:58

Im sorry for that, thanks for learning me. You often find where to analyze the problem or where the problem occurs in the headers. Does authentication between the mail servers work? is there any dkim or certification errors? – Carl Abrahamsson Jun 28 '13 at 20:30

if you issue $ host example.com what is the output of the command? – karatedog Jun 28 '13 at 20:37

The Failure notice is just saying your recipient address can not be found. And the problem is on the domain name, aka the part after @ sign.

Maybe you misspell the email address? Or yahoo's servers are having difficulties resolving the domain name...

Yeah, its definitely not misspelled, I made sure of that. – riseagainst Jun 28 '13 at 19:57
    
Agreed: the recipient is the one that ought to have an MX record. (An A record may be supported by some software, as a fallback. Some people don't like using that; An record is definitely preferred.) Originator/Sender doesn't need MX records, or even A record, for SMTP (mail), although such things might be nice for approval by certain anti-spam techniques. Definitely more crucial for the recipient, though. – TOOGAM Mar 14 at 21:06
