Hmmm, `dnsdomainname' returns "(none)" here;  Does it work for you?

Running `domainname' instead seems to do the right thing though...


It would probably be safest to simply mirror how it's done @
notmuch-config.c:313, but that seems rather excessive.

Agreed, much safer;  `grep' might return multiple results.

How about this? :

  #+begin_src sh
    fallback_name="$(getent passwd ${USER} | cut -d ":" -f 5 | cut -d "," -f 1)"
    test -n "${EMAIL}" \
        && fallback_email="${EMAIL}" \
        || fallback_email="${USER}@$(hostname).$(domainname)"
  #+end_src


Peace
