I have a question. What are the possible interactions between group names, aliases names and shared mailboxes names ?
Here is an example. I configured a shared mailbox ‘com@domain.tld’ that can be accessed by users belonging to the group ‘com@domain.tld’ (same name). I see potential problems especially with the ‘create alias’ checkbox in the shared mailbox configuration page. Don’t you ?
The general rule is: Defined aliases have higher priority over user and group names.
Check out the new cockpit Mail app to see how this feature integrates with existing objects!
Yep that’s what I’m discovering 
Do you mean that we can test it ? Or do you refer to the screenshots ?
You can install it from the testing repository. As such, I suggest to prepare a testing environment!
Sure. Txs, can’t wait !
