Mail rejected by policy error
Posted on 2008-06-23
Occasionally over the last week we have been getting the following error when trying to send emails:
You do not have permission to send to this recipient. For assistance, contact your system administrator.
<xxx.com #5.7.1 smtp;550 5.7.1 Mail rejected by policy: v=1.0 c=1 p=..............>
Any suggestions as to what is causing this? Thanks a ton, in advance.
