This could be mitigated by configuring the mailserver to require TLS, couldn't it?

Also a thought that just came to me: Taking mailserver which are configured to deliver via hidden services as described in https://www.void.gr/kargig/blog/2014/05/10/smtp-over-hidden-services-with-postfix/ but make the hidden services use HidServAuth and HiddenServiceAuthorizeClient to exclude spammers.

On the website it says that it is "non-SMTP", but naif's requirement was to sent out SMTP mail in the end, wasn't it? So how would that work?
