Method of processing an e-mail to determine a categorization thereof including a sender type and a message type, comprising: receiving an e-mail including a header having header fields and body having content; if the e-mail is not junk e-mail, determining the sender type of the e-mail from potential sender types, via first analysis of the header and the body including application of at least one first complex rule, each applied first complex rule including elementary rules specific thereto, at least some of the elementary rules specific thereto including regular expression analysis; if the e-mail is not junk e-mail, determining, a message type of the e-mail from potential message types, via second analysis of the header and the body including application of at least one second complex rule, each applied second complex rule including elementary rules specific thereto, at least some of the second elementary rules thereto including regular expression analysis. |

1. A method of processing an e-mail message to determine a categorization thereof after a determination whether the e-mail message is junk e-mail was made, the categorization including a sender type and a message type, the method comprising:
receiving an e-mail message by at least one server, the e-mail message including a header having a plurality of header fields and body having content; if the e-mail message is not junk e-mail, determining, by the at least one server, the sender type of the e-mail message, the sender type being one from a plurality of potential sender types, via a first analysis of the header and the body, the first analysis including application of at least one first complex rule, each applied first complex rule including a first plurality of elementary rules specific to that applied first complex rule, at least some of the first plurality of elementary rules specific to that applied first complex rule including a regular expression analysis; if the e-mail message is not junk e-mail, determining, by the at least one server, at least one message type of the e-mail message, a message type being one from a plurality of potential message types, via a second analysis of the header and the body, the second analysis being distinct from the first analysis, the second analysis including application of at least one second complex rule, each applied second complex rule including a second plurality of elementary rules specific to that applied second complex rule, at least some of the second plurality of elementary rules specific to that applied second complex rule including a regular expression analysis, the second plurality of elementary rules being distinct from the first plurality of elementary rules, the determination of the at least one message type being independent of the determination of the sender type; and determining the categorization of the e-mail message, the categorization including the determined sender type of the e-mail message and the determined at least one message type of the e-mail message. |
