"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.

Hello all,
Just a minor thing. Not a big deal, because everything works fine, and I feel secure with my setup.
But, I get this error message pretty much throughout the day/night, which appears to come from my own mail clients (desktop or mobile). I would like to resolve it, because it must me something (that is not good--that I may not understand), that may have other ramifications.
So, here it is.
date time myserver dovecot: imap-login: Debug: SSL error: SSL_read() syscall failed: Connection reset by peer
Anyone have a suggestion of what this might hint to, other than obvious SSL. I tried parsing through various logs, but the most I find is just this single line.
I can produce it, whenever I close my email client.
Thanks in advance.
