All,
our dovecot installation provides a bundle of intermedia CA certificates using the ssl_ca option.
2.3.0 does not supply the bundle, resulting in various clients either complaining about an unverifiable server cert, or quietly not connecting. The log has
Jan 5 17:01:46 Bounce dovecot: imap-login: Disconnected (no auth
attempts in 0 secs): user=<>, rip=XXX, lip=YYY, TLS handshaking:
SSL_accept() failed: error:14094416:SSL routines:SSL3_READ_BYTES:sslv3
alert certificate unknown: SSL alert number 46,
session=
We fixed the issue by downgrading to 2.2.33.2.
Cheerio, hauke
