[exim] Debian packages for Exim

Hi, list!

I want to install Exim on a Debian server.
Unfortunately, Debian uses a (relatively!) old version of Exim, an I can't
use some features...

I don't want to compile Exim on this Server, if it is possible, so I'm
looking for a repository with the last version of Exim as Debian package.

Does this repository exist? Can someone suggest me one?

Thanks a lot in advance!
