Bug#403072: exim4-daemon-light fails to use equifax SSL cert/key obtained from "1&1" hosting

[Felix Palmen]

Package: exim4-daemon-light
Version: 4.50-8sarge2

When trying to use the equifax key/cert, STARTTLS triggers the following
log:

2006-12-14 13:03:29 TLS error on connection from pd9e39091.dip.t-dialin.net
	(palmen.homeip.net) [217.227.144.145] (cert/key setup:
	cert=/etc/exim4/exim.crt key=/etc/exim4/exim.key): Base64 decoding error.

It works fine when compiling the package with OpenSSL instead of GnuTLS.
So please provide optional "contrib" daemon packages built with OpenSSL,
because this seems to be more compatible than GnuTLS.
