[Dovecot] Dovecot broken with newer OpenSSL

[Brad]

After updating my system from OpenSSL 0.9.8j to 0.9.8k Dovecot has
stopped functioning properly with TLS sessions. The version of Dovecot
does not seem to matter as I tried 1.1.11 - 1.1.14. Other programs using
SSL/TLS such as Postfix and lightty still work fine when built with the newer
release of OpenSSL. The IMAP client doesn't matter. For the time being I
have gone back to .13 linked against older OpenSSL.

In the logs I see messages like the following...

dovecot: Apr 16 23:12:18 Info: imap-login: Disconnected (no auth attempts): 
rip=2001:470:b01e:3:216:41ff:fe17:6933, lip=2001:470:1d:8c::2, TLS 
handshaking: Disconnected
