The new `enforce_canonical_emails` site setting ensures that emails in the canonical form are unique. This mean that if `s.a.m+1@gmail.com` is registered `sam@gmail.com` will not be allowed. The commit contains a blanket "tag strip" (stripping everything after +) it also contains special handling of a "dot strip" for googlemail and gmail. The setting only impacts new registrations after `enforce_canonical_emails` The setting is default false so it will not impact any existing installs.
