Message ID contains sender's hostname instead of the hostname of sender's email address, which is preferred for better privacy.

Sylpheed and Thunderbird both create Message IDs like <some-random-looking-stuff@domain-part-of-from/sender-address>.

You can override this in the Send/Header options of the account prefs.

Ah, thanks, the setting is: "Send account mail address in Message-ID."

Contrary to Sylpheed/Thunderbird it includes the whole mail address (ie also localpart@...), though.
