In the past two weeks, we have been getting NDRs on some email addresses:
"You do not have permission to send to this recipient. For assistance, contact your system administrator.
<mail1.company.com #5.7.1 smtp;550 5.7.1 Unable to relay for jboxer@usercompany.com"
I've looked into MS' KB and could not find any solutions. Any ideas?
We're using exchange 2K, SP3 on Win2K Serv SP3.
Thanks in advance.
