when I have SMTP restrictions enabled then all my wordpress sites that have authenticated TLS email all fail and no email is being sent. if I turn off SMTP restrictions then all main will flow again. to be clear I have the same wordpress plugin on many sites and it is using a username and password authenticated account to send mail with TLS. everything worked great untill WHM upgraded and I had to choose SMTP restriction options. how can I enable restrictions but also all authenticated tls email??
