What is the difference between Aliases and Accounts?
Accounts are actual mailboxes; i.e., user@example.com, and the only limit to user accounts is the space allocated for your 12 Point Design account. ALIASES are virtual mailboxes that deliver mail to a user account. For example: A smaller company wishing to appear larger may have aliases set up for orders@example.com, customerservice@example.com, and info@example.com. Mail sent to these aliases could all be forwarded to user@example.com.
