A US patent granted to Postini, the email security company, could
grant it legal ownership of a large chunk of the methodology
underlying anti-spam and message filtering technology on the market.
...
Postini's patent describes using a modified DNS address to redirect
email to an email pre-processing service which can "detect and detain
unwanted messages such as spam, viruses or other junk email messages".
It covers various actions that could be performed on an incoming
message, based on a user's settings. These include deletion,
forwarding, forwarding of partial messages and mailing to several
addresses. It also covers broadcasting the message to one or more
wireless devices.
I don't know what "Modified DNS address" means exactly, but it sure
sounds like they ahave patented procmail...
Course, I haven't read the patent:
