What is an alias?
An alias is used to forward e-mail to another local POP3. You need to create that POP3 before you create the alias. To create an alias, create a POP3, then add an alias. When it asks for POP Account pick the POP3 that you want to forward the e-mail to. In alias put the local name you want the account to have, if you wanted the alias to be help@domain.com then help would be the name of the alias. If you wanted all e-mail sent to help@domain.com forwarded to myaccount@domain.com you would use an alias. ALWAYS us an alias to forward e-mail's within a domain.
