Gmail filters are great – you can use them for a variety of tasks. From moving selected conversations to specific labels to auto archiving replies – Gmail filters and the auto forwarding feature makes life easy, in case you get dozens of emails every hour.
Gmail has added a security layer in the auto forwarding email procedure. When you try to add a new email address where you want to forward emails from your existing Gmail account, Gmail requires you to first verify that email address.
To add a new email address for auto forwarding email, go to Settings> Forwarding and POP/IMAP.
Once you have added an email address, you are shown the following message:
Gmail sends a confirmatory link to that email address along with a verification code. You will have to click the confirmation link or enter the verification code to complete the auto forwarding set up procedure. Here is how the confirmatory email looks like:
However, if you are using Google Apps premier or Google Apps education edition, you do not have to verify the forwarding email addresses. Regular Google apps users are an exception though. More information on Gmail forwarding can be found here.
