Comment (by jeremyfelt):

 In [changeset:"40594"]:
 {{{
 #!CommitTicketReference repository="" revision="40594"
 Multisite: Validate email before checking against banned domains.

 Previously, an invalid email could result in an undefined index when
 attempting to determine the email domain.

 Props ocean90.
 See #39915.
