We use postfix and transport maps to accomplish this for internal mail routing (bugzilla and RT messages go to an internal web server, user messages to our internal mailserver). The map would look something like: joe@mydomain.com smtp:[ASPMX.L.GOOGLE.COM] mydomain.com local I don't know how to accomplish similar routing with sendmail. In order to solve this completely at the user level, you could write a little bit of perl that opens an SMTP connection to the server of your choosing. You could then use .forward or .procmailrc or whatever to pipe the incoming messages to this script.=20 Good luck, --=20 Chris Cowart Lead Systems Administrator Network & Infrastructure Services, RSSP-IT UC Berkeley --Hmb9n29fjuiORm2l Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) iD8DBQFGr7VlV3SOqjnqPh0RAkJmAKCZN+FfeEouT05VuqtO2nDODwz+9ACeOAYB 6s8Lq4wIk/pVTR0C0XzewSQ= =g+7x -----END PGP SIGNATURE----- --Hmb9n29fjuiORm2l--
