Hi I have two server directors in ring and 5 dovecot servers (2.2.36) IP for IMAP and POP3 is a VIP (keepalived)
What is the best solutions to get realy HA for 5 dovecot servers ? Maby corosync+pacemeker ? But this solution is too problematic and hardcore Why I need HA ? Doveadmin is too lazy and doveadm director does not know that one machine broke down and still sends traffic
