I'm not a debian specialist, but check the TLS protocol offerer by
dovecot on this server. I had the same issue on freebsd when monitoring
a dovecot offering TLS 1.3 even if xymon was build on a server running
the same openssl version offering TLS 1.3.

I replaced the imaps/pop3s test by a perl scripts extension using
IO::Socket::SSL build with the same openssl and it fixed the issue.

I reported this issue on this list but never got any answer.
