Comment (by spacedmonkey):

 `filter_var` is used
 [https://github.com/WordPress/WordPress/blob/b7634470193acd081d8de0b43ddf279c1158c378
 /wp-includes/class-phpmailer.php#L1157 elsewhere] in core.

 `sanitize_text_field` is applied to emails first then `filter_var` is run.
 The idea is to just remove character that are not valid in an email. It
 doesn't do a lot of validation that `is_email`, checking domain length
 etc.
