If you wish to forward to multiple e-mail addresses using Google Apps the best thing to do is to setup a group. You need to be an administrator of this domain before you can create or manage groups.

First login to your Google Apps Dashboard and click Create A New Group.

Enter in the group name, this is simply for your records.

Enter in the group email address, such as info or billing

Enter a description for your records.

Select Team and then also click Also allow anyone on the Internet to post messages

Type in e-mail addresses you would like to add to this e-mail forward or group and the click Add.

We also recommend testing a Google Group after the initial creation.

That’s it tho. You have unlimited groups which makes it easy to manage your email and keep you within 50 users, the max email accounts that Google Apps standard provides.
