Ralf:

Sorry to report this but the test is breaking the build under python 3.

See:  https://travis-ci.org/roundup-tracker/roundup/builds/554042243

The crash reports:

            return address
        try:
>           encname = b2s(name.encode('ASCII'))
E           AttributeError: 'bytes' object has no attribute 'encode'
roundup/mailer.py:38: AttributeError

I committed a change that did:

   b2s(name).encode('ASCII')

but that broke even more places, so I reverted it.
