Error Smtp 550 5.1.0

Delivery to the following recipient failed permanently: user@domain.com Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 #5.1.0 Address rejected user@domain.com (state 14). The Cause: There is no "mail.domain.com" in the dns system.  In my case I was sending the mail via an alias (it was a notification email from the web server).  The receiving mail server sees the email as forged and bounces it. The Solution: Go to the dns system and create a mail.domain.com and point your MX records to that.  It's a bit silly, but it has to be done that way. photo credit: derrickkwa This post originally appeared on the Stronico blog - with the absorption of Stronico into Digital Tool Factory this post has been moved to the Digital Tool Factory blog Written By Steve French This entry was posted on Wednesday, March 10th, 2010 at 11:25 amand is filed under How To Fix .

My DNS is at Godaddy.com. I created a new MX record for my two domains as you instructed. Is there any thing else that needs to be done on the server itself? Thanks Reply Hanan says: July 28, 2010 at 4:31 am More than half modern culture depends on what one shouldn't read. Reply Stolho says: September 27, 2010 at 8:51 am Thanks much for this tip, but can you please clarify your steps? You write: Go to the dns system and create a mail.domain.com and point your MX records to that. It’s a bit silly, but it has to be done that way As I understand: Go to My Account -> Domain Manager Select my domain Click Total DNS Control Add New MX Record (Priority 0 ; Host @ ; Goes To mail.domain.com) Am I right? Or I do somethig wrong or miss some additional steps? Reply Maritime news says: September 28, 2010 at 12:06 pm We've just had the same thing occur - but in our case our mail service was added under an ‘asiapacific' region rather than U.S. There is also a ‘Europe' smtp service. So we had to add new MX records (under Total DNS link from Domain manager) as: MX @ smtp.a

I would say that the recpient address (lfell@unmc.edu) doesnt exist.
