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.

Seems like the likely cause is you MUA is not closing out the session properly. Start looking for "dovecot.*Debug" in your logs and you're going to see a lot of lines (so many that i have them logged into a separate file). -- There is something to be said for grace and respect but humour alway helps - Toby Morris

"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.
