Generic spam plug-in

[Julian Field]

Current thoughts are a function call (with timeout wrapper). It gets 
passed the smtp client ip, the sender and the list of recipients, and a 
ref to an array of lines holding the entire message. The function simply 
returns a number which is added to the spam score along with the 
SpamAssassin score. You can replace SpamAssassin completely by just 
using the generic wrapper and setting "Use SpamAssassin = no". If the 
timeout happens, the score contribution is just 0.

I should also provide some sample code which calls an external program 
to produce the result score. My code will probably just output

smtp client ip address (IPv4 or IPv6)
sender address
recipient address
next recipient address...
blank line
message contents

It will expect one line of input which will either be the return code 
from the program or the contents of the 1 line of output it produces 
which should be a number. I'll provide samples for both, up to you which 
you use.

MailScanner.conf controls should be
Use Custom Spam Detector = yes/no
Custom Spam Detector Function = <name-of-function-call-here>

That should be all you need.
What do you think?
