[feature req] postfixadmin-cli: list domains, mailboxes

[semseysandor]

There is #388 where OP asks if listing "things" (domains, mailboxes, etc.) are possible with postfix-cli, and the only answer is instructions on how to run help, with no clear statements whether it's possible or not.

So I run help:

$ ./postfixadmin-cli mailbox help

Welcome to Postfixadmin-CLI v0.3
---------------------------------------------------------------
Usage:

    postfixadmin-cli mailbox <task> [<address>] [--option value]

	<task>
		Available values:

		view:                View an existing mailbox.
		add:                 Add a mailbox.
		update:              Update a mailbox.
		delete:              Delete a mailbox



	[<address>]
		A address of recipient.

It seems it's not possible. It would be really nice indeed, it could allow complete administration on CLI.

Are there any reasons why is it not implemented?
