"Connection reset by peer" means client breaks connection, not server.
Client expects non-SSL connection? Client somehow fails over to non-SSL? STARTTLS where TLS expected? Client fails to verify server certificate? Or you use misconfigured imap-proxy? Have a look at *client* logs. You may try "openssl s_client -connect server:port -showcerts" on client side. 30.03.2019 15:20, Esteban L via dovecot wrote: > Hello all, > > Just a minor thing.
