Multiple local_scan's?

Is there plans for supporting multiple local_scan's?

I guess this combined with the dynamic loading would probably be the
ideal way, then you could just have a directory for them.

The issue for me was getting both sa-exim/spamassassin and
exiscan/clamscan working. I did it without much effort by renaming
sa-exim's local_scan.* to sa-exim.*, and renaming the function to
sa_exim_local_scan, and then adding to the front of the exiscan
local_scan

debug_printf("exiscan: run sa-exim\n");

retvalue = sa_exim_local_scan( fd, return_text);

if ( retvalue != LOCAL_SCAN_ACCEPT ) {
return retvalue;
}
// return_text is lost
lseek( fd, 17 , SEEK_SET);

retvalue = LOCAL_SCAN_ACCEPT;

basically just call sa_exim_local_scan and then seek back to byte 17
(actually, not necessary in the case of exiscan, but anyway).

So partly, this is a request for this to be easier and/or if it is,
how to do it, and partly this is information for anyone else who
wants to to setup sa-exim and exiscan together.

Enjoy,
Peter.

Looks good to me.

TBH I think that's easy enough! Iff Philip accepts the dynamic shared
object patches, then I guess one can just plug in .so files. Otoh this
might tempt anti-virus vendors to ship binary-only modules--this doesn't
give me a very warm feeling inside. However, if such code crashes an Exim
process it won't be particularly fatal :)

*My* plan is that somebody else should write a local_scan that
implements this. :-) The whole point of providing just one lowest-level
C interface was that other people could then write the fancy interfaces
(to call Perl, to run multiple functions, to do dynamic loading, etc.,
etc.) as third-party add-ons.

It would still be nice if there was an 'official' way of plugging in
multiple scanners. Perhaps you could review any that third parties
develop, and 'bless' one of them.
