Setting that socket 0660 is the obvious solution but perhaps there is a more secure way you would recommend eg chown dovecot? I'm guessing this would also need updating in the documentation as afaik our setup should be pretty standard.

Yeah, the auth-userdb socket default permissions aren't usable pretty much anywhere. In v2.1 it's better, but still not as good as they could be. I'm not sure what the best solution for this is.

I was doing some testing yesterday & discovered that when I restart a dovecot instance it doesn't have any persistence (eg resync the lookup table with the other directors or do a save/restore from disk) so you are basically starting from scratch again which would be very bad in our setup.

You mean if you restart one director some of the state is lost in all of them? I think v2.0 had some bugs related to this, but they should be fixed in v2.1.

If you mean that if you stop all of the directors and state is lost when restarting then yes, that does happen. You can run "doveadm director dump" to get the current state and after a restart run its output to get back to the same state.

What state specifically are you talking about anyway?
