Answer 1

If the mail is on your server, you can do anything with it. If on external servers - what the hoster will allow.
For your server, so that all unknown boxes fall into one - it is configured with one line in the config. To answer on behalf of [email protected] and others - well, you will have to create an info user on the server, give him a password, set up a connection to the mailbox - and good luck.
