A method and system that provide an accessibility gateway to Internet e-mail through the use of a web intermediary server. The web intermediary server preferably includes server-generated applications for modifying accessibility settings for supported client devices, registering the user for authority to use the intermediary server services, and generating mail web pages capable of allowing access and use of the Internet mail server. A request for e-mail from any mail server is sent from the client device to the intermediary server. The intermediary server retrieves the requested e-mail from a mail server, transcodes the server-based e-mail into a web-based e-mail, and applies user-defined transformations to the e-mail for accessibility, which is then sent back to the client device. If the e-mail is from a secure mail server, the intermediary server functions as a proxy for the user device to establish the requisite secure connection with the mail server.
