This cPanel Tutorial is about how to setup an email forwarder. Email forwarding simply means that one email address will send it’s mail onto another email address. Common uses of this are generic email addresses such as email@example.com that forward to several different individuals email addresses. Or when someone’s email address changes, and they still want to receive emails from their old address. It can simply be forwarded to their new address. I always recommend that if you are using a forwarder then you shouldn’t setup (or keep) a fixed email account that you aren’t going to connect to and download emails off the server. If you don’t download emails off the server your fixed email inbox will fill up and your account will stop receiving emails once you’ve reached your account drive space limit.
This video explains how to use the disk space usage feature to find out where your account size is being used. Usually it’s either emails or files using up your account space. But you need to be able to find out exactly so that you can take action. Either remove the files / emails, or if it’s legitimate account growth, upgrade your account.
