I have switched to the community channel. My Gromox version is now:
gromox-2.46.100.gf2377b4
However, this issue is not solved. Out-of-office replies are still sent out for messages that were sent to a group.
I suspect there is a misunderstanding, so I will give an example:
We have groups for our company departments, e.g. "sales@company.de". Ten people are members of this group. Five are currently on holiday, the other five are working.
Somebody sends a message to sales@company.de. They will now receive five auto replies with an out-of-office message for each individual sales employee who is on holiday. That's what I would like to turn off. It's fine to receive OOF messages for messages sent directly to an individual's personal address, but when people send messages to a group address they should not receive OOF auto-replies. This is how it used to work with MS Exchange and I believe it should work the same way with Grommunio.
I think that the changes mentioned above regard messages sent to mailing lists managed on the sender's side, not messages sent to distribution groups managed on the receiver's side.
