I have set OMV email notificaton and set 465 port with enable ssl/tls.
But it's will get some errors.
CLIENT wrappermode (port smtps/465) is unimplemented
instead, send to (port submission/587) with STARTTLS
It's test mail will deferred and show "while receiving the initial server greeting" message.
I have setup at thunderbird client with 465 port and enable ssl/tls.It's can send it.How to fix it?
