We run a cyrus-imap 2.5.11 server under FreeBSD and we are experiencing issues
with TLS/STARTTLS negotiation failed entries in the log, which show as timeouts
on the client side. It’s all different email clients and even our monitoring
experiencing these failures. Other TLS services (https mostly) on the same
server do not have these failures. There are also times when these errors ramp
up and happen to most TLS clients, which is only solved by restarting cyrus.
Has anyone else experiences these issues or have any tips on where to look to
figure out the root cause?
