Hi,
It seems like suddenly my QMT installation started acting up and reject
mail (several days now). It does not deliver bounces but reports that
the sending server, e.g., Yahoo, etc, could not connect to send mail.
There is no MTA code in returned mail, at all. Initially, Gmail was
having an issue, as well, but now seems to be able to send mail.
I am convinced it was due to some package upgrade, but I am at my wits
end to figure out how to fix this. Any hints would be appreciated. The
certificate file is Let's Encrypt certificate I have used for some time
now and key packaged into PEM file.
Current package versions are (some upgraded recently, as I was trying to
fix it with no success):

P.S. In the Spamdyke logs, I see that the TLS connection has been
established but it times out:
