How to retrieve message_id from sent emails?

I am using the IMAP extension to transfer incoming emails from my inbox to a
database table in the CRM application which I am developing. I shall have
screens to view the emails, usually related to a particular customer. I
shall also have screens where outgoing emails can be composed before they
are sent out.

When I receive a reply to an email I can use the in_reply_to field to relate
it back to the message_id of the original email, but this is only useful if
I know the message_id of that email. The value for message_id is not
available until AFTER the message has been sent out, so how do I capture the
message_id of the email which I have just sent?

You may define the Message-Id: within the headers:
$headers .= "Message-Id: some_value@yourdomain.com\n";

I generally use a string like:
time()."_uniqueid@domain";

You can use headers to perform lots of tasks for you but you can
seldom control what is returned in a response.

The purpose I have in setting the Message-Id is to identify users in
the event a bounce which is parsed by a script piped from a
Return-Path address.

Mail servers generate message IDs for messages that don't have one. If
the mail already has one, a new one won't be generated. (Note: properly,
you'll want to ensure that the message ID is forever unique. FQDN and
microtime() will probably do nicely.)

Whenever you look at a beautiful woman,
always remember that somewhere, someone is tired of her.
