dovecot - Apr 2014 - Multiple Instances Of Dovecot On One Messagebase

Hello,

I would like to run multiple instances of Dovecot with same message base
(maildir format)

Will this set up work or would that destroy message base?

Intention is to offer different authentication methods to users,
username/password and client certificates. Those instances should run on
different IP addresses which is supported by Dovecot.

Unfortunately Dovecot does not allow different auth configs in "local
<ip> {}" sections.

best regards
Christian
