Replication

Hello, 

I try the replication of two Dovecot servers, but some errors always
appear. Maybe someone here has an idea what's going wrong. 
As an MTA I use OpenSMTPD.

Thank You
Silvio

Replication

Hi Silvio!

Can you please send me dovecot-sysreport ran against the core file?

Please see https://www.dovecot.org/bugreport-mail/ for more information on how
to get the core dump and where to find dovecot-sysreport.

Replication

Make file 90-replication.com on primary and secudary mail server laik in 
example (change ip - or put hostname and password)

# Create 90-replication.conf

nano /etc/dovecot/conf.d/90-replication.conf

plugin {
   mail_replica = tcp:ip:12345
}

service replicator {
   process_min_avail = 1

   unix_listener replicator-doveadm {
     mode = 0600
     user = vmail
   }
}

service aggregator {
   fifo_listener replication-notify-fifo {
     user = vmail
     group = vmail
     mode = 0666
   }
   unix_listener replication-notify {
     user = vmail
     group = vmail
     mode = 0666
   }
}

service doveadm {
   inet_listener {

   }
