how can I create a forwarder?

Hello,

I configured postfix on an Ubuntu 12.04 with Sql and courier,spamassassin+amavis.

All is working well, but I need to forward all email incoming from info@mydomain.com to another email address, that is a mailing list running by mailman on same vps, so all people can read the mail incoming from info.

the "info" mailbox is configured in the users table of the sql, instead the mailing list are configured on the "alias" table.

How can I do for telling postfix to forward all message from "info" to another email address?

thank you!
