Currently notmuch tries to make a guess for a default email address based on the "fully qualified hostname" of the host it is running on. This is roughly equivalent to running "hostname -f". I have observed two things 1) It's a bit flaky. There are various functions (gethostbyname, getaddrinfo) that work in subtly different ways. We've tried three different setups in the test suite to test this, and none of them work everywhere. 2) It doesn't seem that useful. The number of people running notmuch on hosts that can (and want to) receive email seems pretty small. Furthermore, it's not obvious we're going to get the right name. For example on my laptop it returns "zancas.local", which is only routable on my home LAN. I could be wrong about 2, though. If you actually find this to be a useful feature, please reply to this thread. If people agree it's generally not useful, I'd propose to replace it with some simpler default like "localhost" [1], equally useful to for testing, but simpler to implement and test.
