I have had a few problem with exim4 and various phone mail clients (Windows Phone in particular) that seem to result from bad mail clients together with GnuTLS. I'd like to recompile exim4-daemon-heavy to use OpenSSL to see if that helps anything.
Now, I've gotten used to debian's packaging system and am unsure on how to do this. I've downloaded the exim4 source using
apt-get source exim4. I then edited the file Debian/rules to uncomment
OpenSSL = 1.
Then I tried
make, but was told that I need to copy the template
Local/Makefile and edit it to my taste. My taste would be a drop-in replacement for the existing and running exim4-daemon-heavy, just using OpenSSL. And here I am stumped as there are quite a lot of options there and I don't like to break my email setup more than neccessary.
So... what can I do to make this test?
