SpamAssassin 3.4.5 (2021-03-20) Found that lint did not catch a "typo" I made in a "wildcard" email address in the directive "whitelist_auth"
Intended to enter an email address in the form"*@some.mail" but entered"^@some.mail" instead. Lint did not complain. Perhaps the caret character is valid and has some meaning in that context I'm not aware of, but thought I would mention it.
