Yes

If you want to install exim from source, it's best to remove
the existing exim3 entirely. Build a dummy exim4 package
using 'equivs' that says

Package: exim4
Provides: mail-transport-agent
Replaces: mail-transport-agent

Now remove exim (dpkg --purge --force-depends exim) and install
the dummy package with dpkg -i

You now have no mail system on your box, but the dependencies
are satisfied, so you can install exim4 from source.

I found one or two unofficial exim4 packages using Google.
I packaged exim-4.10 myself too - you can find it on
ftp://ftp.cistron.nl/pub/people/miquels/debian/cistron/

No guarantees on anything especially not on what will break
if the exim-maintainer puts an official exim4 into Debian
and you upgrade to it.
