You're right; certificate verification was turned on on my end simply because I'd never had a reason to turn it off (since in recent times the majority of my mail goes through their gateway, which has never presented an invalid
certificate to me before).

Message submission is very different to inter-domain SMTP. There's no MX indirection, so the TLS certificate actually verifies the correct name,
and certificate verification is normal on the client, and correct
certificates are normal on servers. A much better situation.


Sure, but, in that case, it's also perfectly valid to load the self- signed root certificate for that SMTP server's cert. chain into the trusted roots
