Hi,
Since I upgraded a system to Debian 10 running Xymon client 4.3.28, my Xymon server (running version 4.3.28 on Debian 10) reports errors for IMAPS & POP3S tests.
This is weird, because I have another server, running Xymon 4.3.28 too, that is not reporting any issue.
My IMAPS & POPS3S daemon is dovecot 2.3.4.1-5+deb10u1
It is quiet complicated to find the logs for this test, so I don't know what is going wrong.
Sometimes, the test goes green for few minutes.
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.
