..or even the "Linux distribution", considering how eg apache is packaged.

I don't know if such modifications would make it into Philip's Exim,
though. I quite like the argument "if you can't build an MTA, you
shouldn't be admin of one"--just think of the extra noise on a list such
as this should Red Hat offer packages for exim, exim-mysql, exim-maildir..

Otoh I do like the local_scan being a dynamic shared object: it "would be
nice" to be able to plug more than one such object into an Exim, so that
you have lots of small bits of obviously correct code--maybe one for your
virus scanner, one for SpamAssassin, one for some-sort-of-PGP-validator,
etc--and you can just chain them together.
