If your users are stored in MySQL, couldn't a variable be added to the dovecot-sql.conf section to do something like "user_query = SELECT home, uid, gid FROM users WHERE userid = '%u' and ip='%ip'"? I realize the %ip would have to be added, but that should be an easy addition. Then you can just put an ip range or single ip in the MySQL table from which the user is allowed to authenticate.

Hi,
Is there any possibility to limit access to mailboxes by user-spesific ip addresses?
So, I'd like to have a configuration which by default restricts reading emails to company's own ip-address range. So far, this could be achieved by a basic firewall rule, but not any more the following:
However, there is need for a few users to access their emails from world-wide internet, so there should be a possibility to define for certain users an option to skip the allowed address range check.
