Use Rules to Automatically Forward Messages to Another Account

You can use Inbox rules to automatically forward or redirect your messages to another account.

After you sign in to your account, click Options, and then click Organize E-Mail.
On the Inbox Rules tab, click New.
Under When the message arrives, and, select Apply to all messages.
Under Do the following, select Redirect the message to.
In the Address Book window, double-click the address you want your mail redirected to. If the address you want doesn't appear, you can enter the e-mail address in the To field.
Click OK to save your selections and return to the New Inbox Rule window.
Click Save to save your rule and return to the Inbox Rules tab.

Redirecting and forwarding are not the same:
- Messages that are redirected will appear to come from the original sender. When you reply to a message that's been redirected, the reply will be sent to the original sender.
- Messages that are forwarded will appear to be forwarded from you. When you reply to a message that's been forwarded, the reply will be sent to the address that the message was forwarded from, not to the original sender.
A copy of messages that you redirect or forward will remain in your Inbox. This means that your mailbox may reach the storage limit set by your administrator. If it does, new messages will be blocked and returned to the original sender; they won't be redirected or forwarded to your other account. To continue receiving new messages, you'll have to sign in to your mailbox and delete some messages.
