Situation:

We will be switching to Dovecot proxy + Director with three email clusters - each cluster will host different email domains and users - with CephFS storage.

Problem:

A Director instance has one 'director_mail_servers' setting, meaning I could only use one set of email servers, while the set of email servers in the cluster depends on the client's domain. (The reason I use Dovecot proxy is so people can use the same IMAP/POP/SMTP hostnames; regardless of which email server / email cluster they're hosted on.)

Question:

Is it possible to set 'director_mail_servers' based on the client's email domain?

Met vriendelijke groeten,

William Edwards
