I've attached patches to fix both of these bugs. Patch 1 stops apt-listchanges from throwing an exception when /usr/sbin/sendmail doesn't exist. This allows the default apt-listchanges configuration to work on a system that does not have an MTA installed.
Patch 2 moves "exim4 | mail-transport-agent" from Recommends to Suggests, since apt-listchanges now works just fine without an MTA. Patch 3 changes "exim4" to "default-mta" in Suggests. For convenience, I included updates to debian/changelog in these patches. This will introduce conflicts with any new debian/changelog entries added before applying these patches, but those conflicts should prove trivial to resolve. Thanks, Josh Triplett
