Where should a Message-ID be added on an outbound SMTP message?

[jeremy156]

If I submit a message into localhost using SMTP, it appears Exim is not creating a Message-ID as I thought it should. My understanding is that it should always create a Message-ID for a message in which it's missing.

Here's the header of a message submitted in this way, to a Gmail recipient - you see Google had to create a Message-ID. The same behaviour for other receiving mail servers - they all have to add their own Message-ID.

Surely the Exim server on localhost should create the Message-ID?

How are you creating the email? Did you look at the exim logs yet?

The behaviour is the same if I create the message by hand, or using the Perl module Mail::Sendmail which uses SMTP to submit (not the Sendmail binary).

The Exim "mainlog" appears to show as normal, although I don't honestly know what I'd be looking to see differently there.

Aren't you confusing message id (http://www.exim.org/exim-html-curre..._receives_and_delivers_mail.html#SECTmessiden) with Message-id header line?

Check this http://www.exim.org/exim-html-current/doc/html/spec_html/ch-message_processing.html as you might want to add

control = submission

to your exim.conf in order to get Date: and Message-ID: header lines added if they are missing

Good spot - that's exactly it, thank you! I didn't realise I was confusing two things.
