As an exercise that's fine, but in this particular case it is calling
for trouble. There are some role addresses that should have lower access
thresholds, so I'm fine with the test. Even more, it might be useful
to check whether the address given ends in a valid TLD and/or an MX RRSet for
the domain name eists.
