Scripting Mail.app on 10.3.2?

[Paul R Brown]

I would like to be able to use bogofilter directly from within Mail.app 
for a number of reasons, and because AppleScript doesn't have a concept 
of pipes (do shell script can't handle input over 64kb), I'd like to 
find a solution to run a call-back from the command line of the form:

	program a1 a2 a3 | bogofilter -Ns

where program is asking Mail.app for the raw source of the message from 
account a1, mailbox a2, and with message id a3.  This would then be 
called from AppleScript with do shell script.

Possible with perl and Mac::??  Needs AppleEvents and I'm better off 
with C?  Where do I start?
