Message-ID: is one of the few required headers. If the MUA fails to supply it then the first MTA should do so. Threading relies on the In-Reply-To: which is supposed to contain the contents of Message-ID: from the message being replied to. If the MUA fails to create it then nothing else can. _______________________________________________ gnucash-user mailing list gnucash-user@gnucash.org To update your subscription preferences or to unsubscribe: https://lists.gnucash.org/mailman/listinfo/gnucash-user If you are using Nabble or Gmane, please see https://wiki.gnucash.org/wiki/Mailing_Lists for more information. ----- Please remember to CC this list on all your replies.
