Hello,
I have dovecot replication working fine between 2 servers with LDA configured to sync mail coming from Postfix.
These 2 servers are used in master/slave mode - only the one server is used by IMAP clients and the second server is just a backup in case of failure.
Second server is also MX backup and it happens that incoming mails come from it via Postfix and get synchronized with the first server.
I would like to include third server as backup. How could be done while mail_replica accepts only one host?
