wonder why this is patentable?
Perhaps just because someone has the Chutzpah to try to patent it and
the patent office hasn't a clue. Technology of all sorts has moved too
quickly for the patent office and/or the patent laws to keep up. Another
example is a U.S. company that uses recombinant DNA to put an unusual
color in a bean. Then they patent it and sue a Mexican company and block
imports of a bean that the Mexicans have been growing for generations.
That's just nucking futs.
sounds like preque filtering available in
every mta since the early 90's...
looks for 'helo/mailfrom/recpt to' then drops or accepts connection.
Why are software ideas patentable, anyway?
It is only to steal $$$ and to stop newcomers, which is the exact opposite
of the original meaning of patenting...
or stop others from doing what they've been doing all along and gain a
competitive edge in the process or make them pay. All of which works iff
the patent office hasn't a clue.
Have a read to http://www.nosoftwarepatents.com/ . It is an EU-based
organization, but motivations are the same regardless of nationality.
Here in EU we have a lot of (zealous?) public officers attempting to
introduce software patens in any possible way.

Abstract:
The spam blocker monitors the SMTP/TCP/IP conversation between a
sending
message transfer agent MTA-0 and a receiving message transfer agent
MTA-1; catches MTA-0's IP address IP-0, MTA-0's declared domain D-0,
sender_address A-0; and recipient A-1; and uses this source and content
based information to test for unsolicited messages. It interrupts the
conversation when MTA-0 sends a command specifying the recipient (an
"RCPT" command) and uses the various test results to decide if the
message is suspected of being unsolicited. If the message is suspected
of being unsolicited then it logs the rejected message, sends an error
reply to MTA-0 which forces MTA-0 to terminate the connection with MTA-
1
before the body of the message is transmitted; else it logs the allowed
message, releases the intercepted RCPT command which allows the
conversation between MTA-0 and MTA-1 to proceed.
