Can not send encrypted email through a smarthost


(Vasco) #1

I don’t know if it is a implementation problem, a bug or a configuration problem bur here we go.

Can not send email through a smarthost, port 465 (SSL)

Error in /var/log/maillog
Jul 23 22:47:44 gemini default/smtp[7792]: CLIENT wrappermode (port smtps/465) is unimplemented
Jul 23 22:47:44 gemini default/smtp[7792]: instead, send to (port submission/587) with STARTTLS

Port 25 (unencrypted) works well
Can not test port 587 (STARTTLS) because is not suported by the ISP

That is a Postfix SMTP client limitation: no smtps support for smarthost, only STARTTLS!

Additional info and workaround here
