#48951 new feature request

email_too_short is not good email validation candidate

Description

Currently, both is_email and sanitize_email will invalidate/sanitize valid emails:

'admin@mailserver1'
'm@m'

Both are valid emails. ICANN just discourages using them.

The problem comes when you work with decoupled WordPress, and the front end is using custom validation that allows such emails, but WordPress doesn't so you don't have consistent behavior. Plus this is just wrong, as the official specification allows such mails.

WP runs filters in both is_email() and sanitize_email(). If necessary, you can run a filter on either of these so that if the $context is 'email_too_short', you return true instead.
