Email forwarding let's you forward emails sent to an address, to another address or multiple addresses. It makes you to look more professional by creating separate department addresses for a business and forwarding all of their emails to one or more other boxes which can then filter and organize based on those addresses. It allows you to forward mail to an external address at another host or ISP, it allows you to send copies of a message to multiple addresses, etc. It can also come in handy to forward mail to another person while you are on vacation.

Forwards are setup in Cpanel under Mail => Forwarders.

Normally, a forward will just forward the message. Sometimes, though, it may retain a copy in the forwarded box. To avoid this, you can setup a forward for an email box that does not actually exist in your domain, one that you haven't created.

To forward to multiple addresses, use a comma to separate the addresses. ie mailbox1@mydomain.com,mailbox2@somedomain.com

To force a box to keep a copy and forward a copy, set it up as mailbox1@mydomain.com>>>\\mailbox1,mailbox2@wherever.com The backslash is what makes it work.
