Hello!

I've got a problem to run syncing between both dovecot services on the separate servers. The error indicates to the problem with SSL.

Directly using openssl command to connect from one server to other and vice versa is passed without any errors.

OS: FreeBSD 11.1-RELEASE-p4

Dovecot: 2.2.33.2_2 and the older one dovecot-2.2.32.1_1 (or similar) - build by ports.

OpenSSL: 1.0.2k-freebsd 26 Jan 2017

dovecot: doveadm(10.18.1.15): Error: doveadm client disconnected before handshake: SSL_accept() failed: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol

dovecot.conf (on both servers):

mail_plugins = $mail_plugins notify replication

service replicator {

process_min_avail = 1

}

service aggregator {

fifo_listener replication-notify-fifo {

user = dovecot

}

unix_listener replication-notify {

user = dovecot

}

}

service replicator {

unix_listener replicator-doveadm {

mode = 0600

}

}

replication_max_conns = 10

service doveadm {

inet_listener {

port = 12130

    ssl = yes

}

}

ssl = required ssl_protocols = SSLv3 TLSv1 TLSv1.1 TLSv1.2 ssl_cert =

Thank you in advance for any help.

Kind Regards,
