Proper solution to exim and fetchmail problem.

After some further cogitation, I spoke to the fetchmail author, and it
turns out that it was a problem with fetchmail. He's fixed it in the
next version, soon to be released. Once that's done fetchmail users
on sytems running exim shouldn't need the -mda option to fetchmail or
any special workarounds in their exim config.

Thanks for the assistance.
