Hello,

I have system a which updates database records reading incoming email
title.
This system can read emails if they are in certain formated subject
lines. Some time users do reply with changed subject line which may
not be have ill format. Linking such email became challenge. I am
thinking of adding a special email header which will have requried
data. Most of the user are using GUI email client and are least bother
about headers. I think this will help me to the extent.

Is there any such standard email header?

Thanks

Whatever the Mutt mail reader (http://www.mutt.org/) uses is surely
the most standard there is. It might use several different headers
... yes, the documentation has this rather indirect thing to say about
it:

strict_threads

If set, threading will only make use of the `In-Reply-To'' and
`References'' fields when you ` $sort'' by message threads. By
default, messages with the same subject are grouped together in
`pseudo threads.'' This may not always be desirable, such as in a
personal mailbox where you might have several unrelated messages
with the subject `hi'' which will get grouped together.

For more information, see the mutt mailing lists, documentation, and
the source code. (And I guess any RFCs mentioning those two headers
and their usage in Internet mail.)

So there are MUAs which allow user to change headers. I am looking for
immutable header that propagets throu emails threads.

Thanks

If your people can change the headers as they please, how can you find
a header which they cannot change?

I'm sorry, but I cannot see any better option than to follow the
standards and semi-standard conventions in use out there.

And even if there were an immutable header, people could get around it
by not using the Reply command, but instead starting a new thread with
the same subject.

So if people really want to break up a thread, there's nothing you can
do about it.

If you keep track Message-ID header fields which your system sends,
you can try match them to In-Reply-To and References header fields
on replies.

( Be carefull with format of Message-ID header field if you generate
it yourself. If format is not correct, it can not be used on
References and In-Reply-To fields. )

Is it by design? It is little frustrating :(

rather than starting a new message?

Email is just a text file being sent from user to user. The
interpretation of headers like In-Reply-To is just a matter of common
convention.

I liked this statement. Anyway I solved it with help of procmail
recipe.
I am reading subject and associating that email with record. subject
has
record id. If user manipulated subject line, I will send mail back to
submitter
asking him to provide record id.

Again thank you all for your information. I learnt a lot from this
thread.

I'll come to you for the help :)

Thank You,
Jagadeesh
