I routinely access my accounts from 5 devices, which dovecot doesn't know are 
all "me".

This is rather the point of IMAP.

However, if multiple users are trying to move messages at the same time, that 
may cause trouble, so shared mailboxes are the best way forward on that.

If this is more than two or three people, or if they are in different locations 
and will likely be deleting or moving mail at the same time what I would do is 
share the mailboxes from i...@example.com to us...@example.com, 
us...@example.com, us...@example.com, etc.

For reading and replying there is no issue though.

What I would suggest is that the users have folders on the info account, and 
when they are processing/dealing with an email, they move it into info/user1.

That said, the right way to do this is to put the email into a CRM database and 
use a ticket system (or similar) to assign emails to a specific person and not 
use IMAP at all. Unless you are dealing with a really small pool of people all 
in one location  who can be managed to not muck things up, and even then there 
might be problems, and they may well be catastrophic.

Something along the lines of Zendesk, Freshdesk, etc (though I make no 
recommendations). I don't know of any free/open-source CRM packages, but I bet 
others here do.

Sharing IMAP accounts poses no technical problems, we do that all the time.
It might pose GDPR / confidentiality problems however, depending on the 
type of mails in the account and on the legal situation.

That is self-evident and it is not a problem.

I mean: if I just want to have info@ on the Server and all users

If I want to use a shared mailbox, __ALL USERS__ need an account on

It's better to make a public mailbox for that but that involves more
complex setup
And dovecot is not so admin friendly on this matter from my experience so
far.

access the store. That means you might need to share the info@ credentials with

As Remko points out, you need some sort of authorization to access the 
messages. The easiest is an account on the server, the messages are 
located at.


I would suggest one account for the "info" role, that shares its mailboxes 
to one account per (natural) person. That way, if one person is to deny 
the access, you do not have to change the password and give it to the 
other persons.


If you have other ways of authorization, such as: IP address (remote side 
of connection), think about using those implicit ones.
