Hi,
Do any of you know some (X- ?) header fields that are retained by most/all replying email clients?
For example, imagine a header field called "X-IDENTIFICATION". I would like to fill out this field, send the mail, and then receive an answer mail that still carries the identification I originally gave it.
Does such field exist? Fields that are safe to use by anyone?

You can use "References" header for this purpose. New message ID is added to contents of "References" header on each reply. However, some mailers don't support "References" header and its contents will be lost if a user replied to the message using such a mailer. You can learn more about message threading here.
Best regards,
Andrew

Thanks Andrew, I'll take a look at it. I suppose if you use GMAIL as smtp gateway any values I put into these fields, will be destroyed by GMAIL for "Conversation"handling purposes.

We've just sent a message to our Gmail account and replied to that message through Gmail web interface, then examined the reply. "References" header contents was not cut as well as "In-Reply-To" header. So, most probably, if you put something in "In-Reply-To", Gmail won't destroy it.
Best regards,
Andrew

Thanks for the effort Andrew! Beyond the call of duty I think ;)
I've begun testing some code based on document you gave me.
Thanks again.
