The third fallback was returning if the match was done or not instead of
returning the actual email address that was matched. This prevented sending
the mail to the people included in the CC. This bug only affect those that
dont have Email::Valid.

I initialized $valid_email as undef so it would mimic the behavior of 
Email::Verify->address(), which returns undef if no valid address was found.

Odd, I noticed the same thing this weekend.

I just looked it over, and this is certainly broken in the original. The
first return gives the string back if it matches, the second one evaluates
the list returned by the match in scalar context, and so returns 1 for a
match or 0 for non-match. Besides, the regexps are fishy...

- The first one won't consider 'Joe.Hacker' as a valid local address
- The second one will consider 'Joe.Hacker@example.com"' valid (note ")

Need to make both branches (with and without @) agree here, at least. And
this is certainly severely underpowered... dunno if it merits a better job
(or just bail out if Email::Valid isn't found, instead of kludgeing
around...)

Will propose a fix ASAP.
