dovecot ssl error message from my own connections
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.
Opps, forgot that important requirment! sorry
Dovecot 2.2.27

I don't get that particular message, but in general Debug messages are informational, not errors or warnings. 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).

Thanks! I will have a look.

"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.
