But then mails to domains where I am best preference MX without having
them configured as local domain would also bounce instead of getting
frozen. Personally, I like such mails to get frozen for correcting the
mistake later. Just mail with an MX that resolves to 127.0.0.1 should
be refused.
Yes, it's sick and crazy, but such MX records are getting very popular
lately. How about an option in Exim that ignores such MX records like
records that do not resolve are ignored?
