send-email: Don't use FQDNs without a '.'

Although Net::Domain::domainname attempts to be very thorough, the
host's configuration can still refuse to give a FQDN.  Check to see if
what we receive contains a dot as a basic sanity check.

Since the same condition is used twice and getting complex, let's move
it to a new function.
