Hi,
Are there any plans to support shared mailboxes? It seems not that hard to do in Dovecot: http://wiki.dovecot.org/SharedMailboxes
I'd vote no, because a shared mailbox is almost always just a workaround for a proper help desk or ticketing system – none of which MIAB tries to be afaik.
I'm not sure https://wiki.dovecot.org/SharedMailboxes/Shared meets my definition of "not that hard". :)
You could try it out on your host. Just save your changes before upgrading mail-in-a-box. If it works and is useful, submit a PR!
Personally, I've never seen shared mailboxes work for more than a few months in practice... they seem to create more communications issues than they solve.
I'm pushing back on any new feature requests. This project is complicated enough as it is. :)
