Solution
All Dovecot users should upgrade to the latest version:# emerge --sync # emerge --ask --oneshot --verbose '>=net-mail/dovecot-1.1.7-r1' Users should be aware that dovecot.conf will still be world-readable after the update. If employing ssl_key_password, it should not be used in dovecot.conf but in a separate file which should be included with 'include_try'.
