Hallo,
das sollte beachtet werden:
Configuring System Mail Rules and Mail Journaling
https://support.hcltechsw.com/csm?id=kb_article&sysparm_article=KB0032883Daraus:
"The intent of journaling is to make a copy and only one copy of messages as they pass through the router. Journaling uses flags to mark the state of a message and the rule, "Journal this message," sets this flag. However, it does this ONLY if the flag is not already set. This is because the first journaling-enabled server that sees the message controls the fate of the message. No other servers have a say in the matter. The flag is deleted when the message is delivered to an end user's mail file and therefore is never seen.
When a message goes to another server, it is marked so that it isn't journaled again.
Complications arise when more than one server has journaling and/or mail rules enabled. Normally, if there is a rule set up on Server B to journal all messages, you'd expect just that to occur. But if an upstream mail server, Server A, also has journaling enabled, then any message that was journaled on Server A that goes to Server B will not be journaled on Server B.This occurs even if journaling is disabled on Server A, but the rule is still enabled. That is because the rule on Server A sets the flag, so the rule on Server B won't modify that flag (since it was already set). When the router transfers the message from A to B, it will also modify that flag to a value that will prevent B from journaling the message. "
