So do I, but for other reasons. I refuse to do business with them, though I sometimes have to deal with them through work.
Regardless, according to RFC 8314, the standard is to use port 465 & SSL/TLS. Port 25 was never intended to be used by email clients.
Well, yes it was, back in 1982; see RFC821 and /etc/services but that was "simple" and 'unauthenticated' and "insecure" and hence it was hacked and abused, so we don't use that any more. We use TLS instead.
Notice that port 25 also can use TLS. The use of submission ports can not be justified because of need to use TLS. -- Cheers / Saludos, Carlos E. R. (from openSUSE 15.0 (Legolas))
