 Implementing a mail filter using Ray's Mail Filter and sendmail
Because a milter program works at the MTA level, the sending computer's MTA (and hopefully the sysadmin) is notified of the rejection.
Another reason that a milter program is preferable to a /bin/mail replacement is if your system acts as a relay, a /bin/mail replacement will not filter those messages (since they are not delivered locally).
You should go to the Ray's Mail Filter Home Page and download the version that is appropriate for your version of sendmail (there is one for 8.10 and a different one for 8.11, because sendmail changed the API between the two versions).

Applications are mainly classical lowpass, highpass, bandpass, and bandstop filters which should exhibit approximately linear phase in the passband(s) but not necessarily in the stopband(s).
For the classical filter design methods (butterworth, chebyshev, inverse chebyshev, elliptical) the quantization is applied after the filter has been designed (as most common off-the-shelf filter design programs do).

 Annoyance Filter: Adaptive Junk Mail Filter
The Annoyance Filter is a program which exploits the indelible signature of advertising to identify it before it ever reaches the eyes of the reader, with a very low likelihood of junk mail being confused with legitimate messages.
Incoming messages are parsed precisely like those used to train the program, and based on the words with the greatest probability of appearing predominately in junk or non-junk, a probability for the message as a whole is computed.
Given that Annoyance Filter is standard C++ (and the ubiquity of gcc in any case), porting the program isn't the big problem--it's the integration of filtering with the mail processing system, plus whatever is needed to transform the mail system's archives into the Unix mail folder format the program uses while training.
