Are you getting an "sslcert" column?   It gets generated automatically for
https and similar protocols, but I don't know it that's generated for
smtps.  If it is, you can alert on that column.  You can set WARN and PANIC
number of days in the hosts.cfg entry.

Firstly, you'll see 220 at the very start, and then 250 after sending
EHLO
or HELO. So you were correct the first time, with "expect 220".
Thanks Jeremy, I put this back
Secondly, the mail server uses STARTTLS, so it's not doing encryption at
the point that the EHLO and QUIT strings are sent. The "ssl" option in
protocols.cfg assumes SSL/TLS is present during the handshake,
immediately
after the TCP connection is established, rather than after issuing the
"send" string. Try removing the "ssl" option from protocols.cfg and see
if
that helps.
And when I do this, it "tests green" but apparently no longer is testing
the
SSL certificate.

Is there a way to have xymon test the validity and currency of the SSL
certificate too? Especially with LetsEncrypt certificates, I'd like to
have
warning if there is a problem with the postfix certificate config.

Thanks,

Ben
