so better remove the option to specify more than one host instead let people run over years in troubles until they find out that a logical behavior like for postfix is not given for dovecot's mysql-connections - yes i was one of the who thought "hey both works the same way" until i realized that dovecot has no fun at reboot the replication slave which was intented only as failover and used regulary
*it is* dovecots job if it offers more than one host to handle this in a useful way or not support more than one host, but you can't seriously say "it's not dovecots job" after having a half-baken support implemented Am 29.05.2013 02:52, schrieb Timo Sirainen: > I haven't replied to most of the threads recently.
