Hello there, I just noticed that submission confirmation mails have no Message-ID.
In fact the Message-ID is optional. I didn't know that. However, the RFC also states that the field SHOULD be present. In my experience a missing Message-ID can cause some interesting problems and is usually punished with a bad score in common spam filters. If the submission form doesn't generate a Message-ID, the first MTA should. This could solve some of the occational deliverability problems.
