Normalization Rules

Normalization rules vary by domain. The rules implemented by this package are:

1. "plus" — remove first + mark and anything after it
2. "dot" — remove all . marks
3. "none" — do nothing

Emails are normalized by domain as follows:

1. gmail.com — plus and dot
2. googlemail.com (alias of gmail.com) — plus and dot
3. hotmail.com — plus only
4. live.com — plus and dot
5. outlook.com — plus only
6. all other domains — none
