A system and method are disclosed for protecting e-mail sender identity by redirecting e-mail messages to an e-mail forwarding server via use of customized recipient e-mail addresses. An e-mail message is sent from a user's actual e-mail account to a customized recipient e-mail address. Because an e-mail forwarding server of the present invention is the Mail Exchange (MX) authority for the domain of the customized recipient e-mail address, the e-mail message is sent to the e-mail forwarding server. The e-mail forwarding server contains a database that stores users' actual e-mail addresses and their associated alias e-mail addresses. When the message is received by the e-mail forwarding server, it parses the message recipient's e-mail address to obtain the intended recipient's e-mail address, replaces the message sender's actual e-mail address with its associated alias e-mail address, and delivers the message to the original intended recipient. To the recipient the message appears to be sent directly from the sender's alias e-mail address. Therefore the sender's actual e-mail identity is not exposed to the recipient. When the e-mail forwarding server receives an e-mail message sent or replied to the user's alias e-mail address, it automatically forwards the message to the user's actual e-mail address.
