It is informational only and often unchecked or audited by
organizations.  The purpose is to discuss DNS related issues with the
DNS admin and dots in email user names are considered a wild card and
would simply be compacted so foo.bar at google.com and foobar at google.com
are the same.  As Paul mentions you should escape the period or other
char if needed.
