1. An apparatus comprising:
- an e-mail relay implemented at least partially in a hardware processor, wherein the e-mail relay provides both (i) filtering of unwanted e-mail based on contents of a database and (ii) collection of attributes and derived information for e-mails received by the e-mail relay for addition to the database and for use in filtering of subsequently received e-mails,the e-mail relay configured to, using the hardware processor, categorize individual ones of the received e-mails into at least three categories, including clean, unwanted and borderline, wherein for at least some of the e-mails categorized as unwanted, either or both of attributes and derived information for the unwanted e-mail are added to the database, and wherein for at least some of the e-mails categorized as borderline, the e-mail relay quarantines the borderline e-mail and supplies an intended recipient thereof with an alternate message that includes a URL by which the intended recipient may initiate a retrieval session and specify that the quarantined e-mail is unwanted,the e-mail relay further configured to, responsive to specification by the intended recipient that the quarantined e-mail is unwanted, prompt the intended recipient to classify the unwanted e-mail according to at least one pre-established category.

Abstract
An e-mail relay provides message filtering services to an e-mail network. The e-mail relay monitors incoming communication and intercepts e-mail messages. The e-mail relay compares attributes of the messages to data derived from SPAM messages, which are stored in a SPAM database. The e-mail relay restricts the delivery of messages based on the comparison such as by restricting the delivery of messages having attributes close to those of SPAM messages from the SPAM database. The SPAM database is constructed by responding to user or administrator indications as to whether received messages are SPAM messages.

10. A method of reducing a flow of unwanted electronic messages, the method comprising:
-
receiving electronic messages at a relay and determining that at least some of the received electronic messages are unwanted based on contents of a database that codes attributes and derived information characteristic of messages that have been determined to be unwanted, wherein the determining characterizes at least some of the electronic messages as neither clean, nor unwanted, but rather borderline; updating contents of the database for use in the determining for subsequently received ones of the electronic messages, wherein the updating is based, at least in part, on attributes and derived information for electronic messages received by the relay itself; directing those electronic messages characterized as borderline to a quarantine; and supplying an intended recipient of a quarantined electronic message with an alternate message that includes a URL that allows the intended recipient to initiate a retrieval session and to specify that the quarantined electronic message is unwanted, wherein responsive to specification by the intended recipient that the quarantined electronic message is unwanted, the relay prompts the intended recipient to classify the unwanted electronic message according to at least one pre-established category. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A non-transitory machine-readable medium comprising a plurality of machine-readable instructions that when executed by one or more processors is adapted to cause the one or more processors to perform a method comprising:
-
receiving electronic messages at a relay and determining that at least some of the received electronic messages are unwanted based on contents of a database that codes attributes and derived information characteristic of messages that have been determined to be unwanted, wherein the determining characterizes at least some of the electronic messages as neither clean, nor unwanted, but rather borderline; updating contents of the database for use in the determining for subsequently received ones of the electronic messages, wherein the updating is based, at least in part, on attributes and derived information for electronic messages received by the relay itself; directing those electronic messages characterized as borderline to a quarantine; and supplying an intended recipient of a quarantined electronic message with an alternate message that includes a URL that allows the intended recipient to initiate a retrieval session and to specify that the quarantined electronic message is unwanted, wherein responsive to specification by the intended recipient that the quarantined electronic message is unwanted, the relay prompts the intended recipient to classify the unwanted electronic message according to at least one pre-established category.
