Hi everybody:

I need to change the 'return-path' header of the e-mails I send using CDO in Windows 2000/2003.
I've tried to change the urn:schemas:mailheader:return-path in the mail header, but it doesn't work at all.

I think return-path is changed by the receiving MTA when the sending MTA connects to it for authenticate, but as long as I'm using the local SMTP server included with IIS I don't know how to indicate that...

I tried to use a event sink in order to change this header before sending but all was in vain. The return-path always shows the same e-mail address as the 'From' field, which is exactly what I don't want.

I've search the newsgroup in vain, and also Google News.
It seems that is not possible to acomplish this with CDO (I've found a lot of pages showing how to do it in PHP :-(, will I have to change?)

Any ideas in how to do this will be very appreciated.

Regards.
