An authorized email control system receives email destined for a
particular user. Inclusive, temporary and exclusive address books are
provided for the user. The inclusive address book lists all the sender
email addresses and domains names that the user wants to allow into his
mailbox. If the received email message's sender is listed in the user's
inclusive or temporary address book then the email is placed in the
user's main mailbox. If the sender is listed in the user's exclusive
address book, then the message is deleted. The invention truncates the
body of the received email message to a user settable length which is
sent through at least one extensible message filter that provides a
pass/fail indicator and optionally provides reasons for a fail
indication. If the truncated email body passes all of the filters, then
the sender is added to an accepted sender list. Otherwise, the sender is
warned that its email was rejected and the reason(s) why. The sender's
domain name is then placed on an unaware domain list. The user is
conditionally notified if the sender has been added to the sender list or
unaware domain list, giving the user the option to add the sender to his
inclusive or exclusive address book.
