How to group e-mails by thread?

I need to recognize if email message is an response for message sent by my application, to put it into same email thread (something like gmail does). How can I mark an email or what data let me to recognize if it's an answer for one of previous messages in a thread?

I'm connecting through IMAP protocol, but I can easily switch to pop3 if it will be easier...

+2  A: 

When you send your e-mail, include a Message-ID header with some globally-unique ID for your message.

When you get the response, it should have a References header that refers to your original Message-ID.

The 'In-Reply-To' header of the child should have the value of the Message-Id header of the parent.

There is one another field in header 'References' which contains message ids of all its parent.

you can user either of them as per your requirement.
