When you enter your email address, it would be TRIVIAL to check the

Rightfully so. There is absolutely no guarantee that the server on the inbound (MX) record also handles outbound and/or IMAP. In many cases, these will be different systems.
tell that to ovh, amazon, google, dreamhost, microsoft that have client mta that belive in open ports to custommer only services, i just say go away in iptables
