"You do not have permission..." but with an angle
Posted on 2006-06-14
I have someone who is trying to send to my Exchange 2003 box (@company.com).
When they send a new message, it gets through no problem.
When they send a reply, we get this back:
Your message did not reach some or all of the intended recipients.
Subject: RE: Test message from company
Sent: 6/14/2006 8:53 AM
The following recipient(s) could not be reached:
firstname.lastname@example.org on 6/14/2006 8:53 AM
You do not have permission to send to this recipient. For assistance, contact your system administrator.
<mail.othercompany.com #5.7.1 smtp;550 5.7.1 Unable to relay for email@example.com>
I have dealt with these before, but they were always and 'all the time' thing. This is different, since new messages get through, but replies don't.
I do not yet have a lot of info on the sending server.
I don't believe the problem is at my end. There is nothing in my event viewer, or in any of my logs for my virus/security/spam software.
Any ideas? Is it all at their end? Any suggestions I can pass on?
