Comment:

Natalia's proposal would also simplify implementation of #27029 EAI
address validation. (Or help developers who need that functionality sooner
subclass EmailValidator themselves.)

Django already uses "recipient" to mean a complete email address, possibly
including a friendly display name (e.g.,
django.core.mail.EmailMessage.all_recipients()). The official RFC 5322
term for the part before the @ is ''local-part'', but other common terms
are ''user'' (e.g., existing EmailValidator code), ''username'' (e.g.,
Python's email.headerregistry.Address.username), or ''mailbox''. I'd maybe
go with `validate_username()` and `validate_domain()` to align with
Python's email package.
