Plain and simple.

We have Zimbra 6.0.2_GA_1912.RHEL5_64_20091020161509 RHEL5_64 FOSS edition and forwarding acts in a way i think is a little strange.

UserA@mydomain.com has a forwarding address set to UserA@gmail.com

When UserA@mydomain.com receives an e-mail from an EXTERNAL source (yahoo or gmail for example), the message IS NOT forwarded to UserA@gmail.com

When UserA@mydomain.com receives an e-mail from other user @mydomain.com the message is forwarded to UserA@gmail.com

Any clues? Is that how it was supposed to work?
