I have a strange, strange problem with PGP and ironport server.
Every time my colleague receives a encrypted mail, this mail will multiply himself 10 or times. So the user receives 10 copies of the same mail in a couple of minutes.
Did you have see a thing like this ?
Some errors the sender receives
"The reason for the problem:
5.x.1 - Maximum number of delivery attempts exceeded. [Default] 'Connection Lost'"
or
The reason for the problem:
4.4.2 - Bad connection 'Connection Lost'
Diagnostic-Code: smtp; 4.4.2 - Bad connection 'Connection Lost' (delivery attempts: 7)
