I suspect that servers trying to deliver messages to your server insist on
delivering them using TLS, which you have now disabled. Perhaps the only host
to be excempted from delivering via TLS should be the one of your hosting
provider.
But then, I'd rather have all servers using TLS rather than sending them
unencrypted anyway.
