running alternate dovecot instances on the same server

[Chris Hoogendyk]

I'm posting to the list, but not on the list. I presume that means a reply-all to get to me as well 
as the list?

We have two servers (dovecot --version:  2.2.22 (fe789d2)) that handle email for two different 
departments.

We are transitioning mail service to the University central IT. They need to move accounts in an 
automated fashion and therefore need a master password to our dovecot servers. However, we are 
running with LDAP authentication, and I understand that a master password is not possible in that 
configuration.

Would it be possible to run an alternate dovecot process that would use local account 
authentication, have a master password, and use an alternate port for connecting? Ideally it would 
only read accounts without changing anything, and would not interfere with the operation of the 
other dovecot process. I'm hoping that I could copy the configuration files, make these changes, and 
then launch it manually without any startup scripts in /etc/inetd.conf.

Oh, by the way, we are running Ubuntu 16.04 LTS and have contracts with Ubuntu Advantage for ongoing 
patch support. The dovecot version is from the distribution, installed with aptitude.
