    Thank you!That might be a point where to start :)  I have another
question.
    As standard is not alway followed, I was thinking to handle these
emails in a different way.
    I am writing a news letter program, and I need to handle the bounced
emails I receive, just to alert the user that some emails have not been
delivered.
    I realised that I don't have to handle all the DSNs (Delivery  Status
Notification) I receive but only those regarding the emails I have
sent. For this reason I have added an extra field in the header of the
emails I am sending, so to be able to eventually test it in the bounced
messages. I have done some tests, It seems than the header is correctly
rewrite on the bounce email. Well I am wondering if the orginal message
header is always returned. Any Idea?

Thanks
Marco
