Description:
------------
I had a user who was subscribed as "foo.bar@gmail.com";
however he tried to unsubscribe as "foobar@gmail.com"
and mlmmj-unsub could not find him despite his mail server
believing they are the same address.

I think mlmmj should preserve the known '.' location when sending
emails, however the unsub lookup could be specialized for certain
domains (gmail.com and googlemail.com at least) to ignore '.'
in the usernames when comparing.

I'm no expert on email addresses, but this may be a gmail-specific
quirk list servers need to be aware of.
I'm not sure if other mail servers implement this sort
of normalization; but gmail does host servers for non-google
domains).


The cynic in me believes it's yet another case of
