Message-ID: undefined

Good day,

I’ve been experiencing some malfunction / bug maybe on my Axigen Server.

The scenario is ALL incoming mails are copied to a specific mailbox we may call “ALL”.

The problem is the messages arrived on some mailboxes (a,b,c) are coming with “Message-ID: undefined”.
While the copy of the message in mailbox ALL is with the correct Message-ID.

How can this happen?

Regards,
Jay

Case closed!

We found the culprit and It was not Axigen who does it.

It is the specific Addon on TB who created this issue.
