Subject: Delivery Notification for

This is a delivery status notification, automatically generated by MTA mail1.mycompany.com on Tue, 17 Jul 2007 15:14:45 -0500 Regarding recipient(s) : jane@abc.com Delivery status : Failed. Message could not be delivered to the domain - abc.com. Failed to accept the recipients.
MTA Response :550

I'm assuming the person we are sending it to is blocking or dropping mail we send to them. i checked out system and everything is processing properly. I've also done a tracert on this domain and it times out about halfway.

Any help would be great

When I see recipients' servers kick out a 550 error, it's usually their own problem. If you're a nice person, you may wish to talk to their technicians and help them troubleshoot.

Sometimes you don't know for hours that you're not receiving mail from the outside world...

I should have elaborated a little more..mail1.mycompany.com is my mail server telling me that their domain abc.com will not accept our message...Right? What could be causing that then if it's on their side??

by cactus pete

Their server refused to accept a message and kicked out a 550 error. Your server recorded the failure with the 550 error.

Otherwise, NONE of your mail would be going out, because of a relay misconfiguration.

I suspect that the remote mailbox is full.
