Hello,

• Set up a pair of servers according to http://wiki2.dovecot.org/Replication -Enabled SSL for both servers
• Dovecot version: 2.2.13 (Debian 8.6)

I couldn't find an option to specify the certificate that doveadm should use when connecting to the other server. Both servers have hostnames that are different, as verified by dovecot --hostdomain(as per the instructions) but use a common certificate when emailclients connect to them (high availability setup). Yes, single server login works as expected, been working for the past few years :-).

Setting up a custom ssl_client_ca_file doesn't work, since doveadm doesn't know which certificate it should send when connecting to the other doveadm. Setting the ssl_client_ca_dir tothe directory with the global CAsdoesn't work either, since doveadm doesn't use the hostname that dovecot actually uses.

The custom self-signed CA works when used outside dovecot(mysql for example).

Is there any configuration thatneeds to be changed in order for doveadm to use a custom self signed certificate?

Thank you
