FYI: Threading Messages Correctly on Thunderbird

[Jarrod]

Dear All,

Just a quick one for the benefit of anyone who might be using Thunderbird
to send emails to the freebsd mailing lists.
Thanks to the postmaster for his/her help on this one.

It seems that in order to have your replies to a topic threaded 
correctly you
need to add a second field to your message header block labelled "Reply-To".
This can be selected from the drop down list that appears if you click "To"
on the left side of a header block entry. (Same as making CC, BCC
fields, etc.)

On the right side of the "Reply-To" entry, paste the "Message-ID" of the
message you wish to reply to. This is present for every message when 
receiving
in the "digest form".

(Not sure about receiving messages one-by-one. You might need to go
View -> Headers -> All in order to see the Message-ID?)

Be sure to include the leading and trailing angle brackets
(ie. the less-than and greater-than signs) !!

Cheers,
Jarrod.
