Yes, it appears to be:

This is Monit version 5.25.2
Built with ssl, with ipv6, with compression, with pam and with large files
Copyright (C) 2001-2018 Tildeslash Ltd. All Rights Reserved.
dh

This is on FreeBSD 11.2-RELEASE, compiled from ports.

One delta between our configs, if it matters, is that your has 'set tls'
instead of 'set ssl' in the 'set mailserver' definition. I don't think
that's significant, as I changed mine, restarted monit, and saw the same
STARTTLS error as before. I also tried commenting out the 'pemfile:'
line in the 'set ssl' definition but that also had no effect.

An openssl STARTTLS handshake works OK from this server's command line.
Output below.

Anything else I need to check in the monit config?

Thanks
