Hi Guilhem,

reportbug allows sending mails using thunderbird/any installed mail client. I
think caff should also offer this option. This would make it easy to use caff
with an mua already configured instead of having to configure it again.

Praveen suggests to add an option to use xdg-email(1).  At first run (if
there is no ~/.caffrc), the tool could ask a question about which mail
system to use, like reportbug currently does.

At debconf, I was suggesting to Robert to use msmtp to configure mta, but
realized outlook (and also google) now require using oauth and this needs using
a python script (I think not packaged as well) to get oauth token. So this
makes using caff much harder for people not having a provider with simple
smtp/tls support (especially for people new to debian). So in such cases, we
will have to just skip using caff.
