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.
