delivery failure; X-Postfix; mail loops back to myself issue
Over the weekend we received a large number of delivery failures with the X-Postfix; mail for [10.101.150.121]: 25 loops back to myself. Has anyone else received this error? What does it mean? Recipient email addresses all look correct. I did notice that a large majority of the email address were for gmail. I have tried to resent a few but still received the error. Also, during this time period we were able to successfully deliver other envelopes.
