For references (and large discussions) it's better to limit it to 1024 bytes, and when it grows over, remove second, third, itd. message id from references list so it's length gets below 1024-3, and insert three spaces in place where deleted message ids were. DO NOT REMOVE FIRST MESSAGE-ID. > Also, apart from the In-Reply-To and References headers, consider > threading on "Re: original_subject" at the same time -- although all > these methods together might be complex to program. This way you could at least group replies for messages not stored, or without references/in-reply-to fields. Just first thread the messages by references/in-reply-to, then group not threaded messages. -- Piotr "Hellrayzer" Dalek Author of ICS-Based Hellcore Mailer - an Outlook Express killer http://www.hcm.prv.pl [EMAIL PROTECTED] --------------------------------------------------------------------- Najwiekszy MOTO-serwis w Polsce >>> http://link.interia.pl/f18af -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
