--- Comment #2 from Mark Martinec <mark.marti...@ijs.si> --- Btw, the rule in 20_head_tests.cf: header __FROM_NEEDS_MIME From =~ /[\x00-\x08\x0b\x0c\x0e-\x1f\x7f-\xff]/ incorrectly hits on properly MIME-encoded display names (like in sample messages here). It should be checking raw text (From:raw) _before_ it gets MIME_decoded. Moreover, it should apply to display name (and comments) only, as the mail address itself cannot be MIME-encoded at all - the only allowed form of an e-mail address is UTF-8 (when mailer supports SMTPUTF8 option). So the rule should be: header __FROM_NEEDS_MIME From:name:raw =~ /[\x00-\x08\x0b\x0c\x0e-\x1f\x7f-\xff]/ -- You are receiving this mail because: You are the assignee for the bug.
