Exim 4 already has the option for including the source code for a
function called local_scan() - which is called to scan messages as they
arrive. Naturally, you can write C code for this function which does
whatever you like. It occurs to me that, from my point of view as an
implementor, this is a better approach, because it does not force any
one implementation on people. The C code can do the job, call embedded
Perl, make use of a dynamically loaded library, or use dlopen() if it
wants to. That means the responsibility for choosing between these
methods (on security or other grounds) is yours, not mine. :-)
