Perhaps one aught to take something like silence_warnings from ActiveSupport, or a simpler implementation, without having to pull in an extensive dependency.

Wherever the Mail gem is producing the messages

Non US-ASCII detected and no charset defined.
Defaulting to UTF-8, set your own if this is incorrect.

Should be silenced in these tests.

Hi, thanks for your interest! Those UTF-8 warnings are fixable, and I have previously fixed them like this: 4c92dc290b760d7545818e74a5f7275f577093a5

Cool, I'll tweak my patch, as I mentioned in the pull req. was hacking late at night and looking for success more than perfection, will adapt and come back with some additional tests.
