Mails not accepted (Milter error)
we have trouble with a Fortimail-VM01 in gateway mode (v6.4.2(GA), build427, 2020.09.01).
Mails from just one sender (important one) are permanently rejected, allthrought the sender domain is on the system white list and also in the gleylisting exempt list. Other senders from the same sender domain are accepted without problems.
Here are some log entries:
