Forwarders:
A forwarder is useful if you want to have several e-mail addresses, such as jim@domain.com, baker@domain.com and jim_baker@domain.com all go to a single POP account. Also, forwarders can be used to forward bob@domain.com to bob@aol.com, which can be useful if you do not want to check several e-mail accounts. You can setup unlimited forwarders with a ProWeb account.
