Using Ubuntu 14.04 is there a way to upgrade exim4 without losing configuration? Preferably through apt.
apt-get --simulate upgrade it shows the package will be upgraded to
4.82-3ubuntu2.4, however the latest version appears to be 4.93 according to [exim.org].
Would the easiest solution be to compile this from source, copying any config files currently in place and just hope that they work with the new version?
