OpenSMTPD doesn't suport auth without TLS. It doesn't even advertise auth without TLS[0]. So to get your server working you need to get an TLS cert (bonus points if it's trusted by your iphone). Add a pki to your smtpd config. Then add something like: ... tls pki $pkiname auth[-optional] ... to at least on of your listen statements.
