Fixes #54 old MSN addresses may start with a digit

Issue #8 details that _new_ addresses may only start with a letter.

I have seen valid emails like '0xxx@live.com' in the wild, which can no
longer be created, but do still exist.

I altered the regular expression to start with an letter or digit.
