bounced email catching

[Rob Imbeault]

Hi Guys,

I am building a script that catches emails. I have access to the email
source and I would like to distinguish between bounced emails, auto-replies
and real replies. Is there a standard that all servers follow for rejected
emails. I am looking for a unique string I can search for like "Mail
Administrator" or "Failed email." Does anyone know or know where I can
look?

Cheers

You may be more likely to find an answer about mail header standards in an
Exchange, Outlook, or SMTP group if not here.

Though, in the meantime [1], the approach I took was to examine the emails I
was getting and then write
a couple of Reg Ex's to cater for them.

I'm able to pull out about 99% of the addresses from the bounce backs.

Trail and error also works - if you make sure your program doesn't delete
the emails you can keep trying until it reads successfully and then do it.

[1] or is that encouraging bad habits?

Finally, I did it in VB.Net - I can't see a reason for doing it in ASP.
