Tracking Bounced Mails to Original Message

Can I trace bounced mail to its original sent message.

I tried matching the subject matter but it does not help as subject for two different emails can be same.

As single pop3 email id is used by multiple alias users for sending messages, this could help me trace the exact sender whose email has bounced.

Please help.

see In-Reply-To header in delivery failure report.
this is a unique string in Message-ID header of originally sent mail.

there is no In-Reply-To in delivery failure report.

Is any additional header needed to be sent at the time of sending email to get 'In-Reply-To' header in bounced back emails.

what kind of bounce are we talking about? delivery failure by remote server or by HMS?

Why do multiple senders use the same account?

POP3 external account is configured for a domain account with multiple aliases. This multiple alias users send messages using SMTP Route for the domain. Need to trace which alias user had sent the bounced mail.

Can hmailserver identify this, as it sends message one by one after applying rules?

open for each alias user an account and force auth to send mail.
with a few scripting in Sub OnAcceptMessage(oClient, oMessage) event you trap sending user, add a pre- or suffix on subject (such as "//u-5//", unique for each user), save message, let it go.
when you see a bounce, you know it was from "user 5" who is jane, joe...
