I'm also interested in cooperation since most people seem to want both
AV and Antispam. Since SA does not seem to add a very large overhead,
it may be feasible to do both. (Caveat: see my discussion with MBM).

That would require Philip to do some work first.

But since SA works on the body too, there would be much less overhead to agree
on a singe MBOXification of the message and then work on the same file ...

I did not mention that the "old" exiscan v2 still works perfectly with exim4.
It does scan outside of the SMTP session, with all the pros and cons
involved.

I am on holiday until June 1, I'll contact you when I'm back and we can
sort out the details then. Maybe PH has some ideas regarding the
modularization of local_scan() ? ;)
