Hi safir,
From the Exchange Administrator,
*)File, New Custom Recipient.
+)On the New E-mail Address dialog box,
-)Internet Address.
Goto Properties of Internet Address.
enter the non-Exchange user's final address. ( username@unixserver.domainname )
Once u fill up that, u will be getting Empty properties for Non-exchange user will come up. Fill the minimum First, last and alias. (here alias is the exchange id)
*) If u want the user to receive the mail on username@domainname, hence u may need to create an secondary SMTP address.
+)Goto E-Mail Addresses tab. (On the property of the user)
-)Select New, and in the box on the Internet Address Properties screen, enter the secondary SMTP address in the format appropriate to the local organization (e.g., username@domainname).
+) Check on that SMTP => Unix address
By this method ur user mail box will be on Unix server. Exchange will reroute the mails from Unix and vise versa.
Limitation : Ensure this is an rerouting mechanism, Hence the sending id should be username@domainname. Change in the Reply-to addresses accordingly.
ALL THE BEST.
Things are very easy, when u know about it...
