[Maciej Milaszewski IQ PL]

Hi
I have two server directors in ring and 5 dovecot servers (2.2.36)
IP for IMAP and POP3 is a VIP (keepalived)

Maby corosync+pacemeker ? But this solution is too problematic and hardcore

Doveadmin is too lazy and doveadm director does not know that one
machine broke down and still sends traffic
