Thanks, Victor.

Sounds like one option would be to setup a separate Postfix instance and relay to it in sendmail based on Sender (using something like this sendmail mod, http://anfi.homeunix.net/sendmail/smarttab.html). The final step is to include/exclude that incoming mail for delivery to either Postini or not based on the recipient's address. Is recipient-based alternate routing possible once the Sender aspect is resolved with the additional internal hop? Any pointers? Thank you, Scott Stirling AT&T, Boston
