In setting up my new mail server, I am getting the following in the logs:
Oct 11 07:10:59 kumo dovecot[5704]: imap-login: Disconnected (no auth
attempts in 0 secs): user=<>, rip=24.53.79.10, lip=172.26.12.90, *TLS
handshaking: SSL_accept() syscall failed: Success*,
session=
I have tried various ssl_protocols entries, but for now have defaulted
back to ssl_protocols = !SSLv3 (the "out of the box" setting).
The certificate (ssl_cert = valid and the same one used by postfix. However, I belive the error
appeared only after removing the self signed certificate and installing
the one I purchased.
Warning: though I was a sysadmin a long long time, it has been a
while! I have not run a mail server in 15 years, but am moving my mail
back "in-house" as I approach retirement! I searched for a forum where
I could post this issue, but only found this list.
