Email regex doesn't match invalid email

[JoschuaGoetz]

The email 'email@-example.com' is invalid because the first part of the domain part is a dash.
@DennisRein Should i fix it and ship the change with a merge when im finished or do you want to fix it ?

[DennisRein]

So the issue is that @-domain emails do get accepted right? If that's the case I'd appreciate it if you could fix it quickly because I am working on other screens right now.

Okay, the issue isn't that important so i will ship the change when i merge into develop.
