I am having intermittent problems with my inbound internet mail routing as follows:
Several times a week, a random message received from the internet and being forwarded to one specific internal mail server will route over and over again at about 30 minute intervals.
Sometimes the messages have deleted from the gateway mail.box after several iterations. Other times, when I am made aware of it, I delete the repeating message myself.
AFAIK, this only happens on messages being forwarded to that one specific site and it has affected several users at that site on multiple occasions. Their annoyance level is rising.
Any ideas? I have created new mail.box(s) at both ends of the transaction without success.
Thanks in advance.
