In the context you are asking, both are names for ports as defined in your services(5) file (or other port name-to-number translation as configured to use by your OS-provided libraries.) $ getent services smtp smtp 25/tcp mail $ getent services smtps smtps 465/tcp > In smtps, all the information pass encrypted? Using key and cert > from tags tls in main.cf? SMTPS is a deprecated protocol for submission which uses SMTP over an SSL-secured connection. New sites should have no need for it, simply tell your users to use submission (587/tcp) with TLS. > Now I have smtp+tls. > smtps == smtp+tls and different port? > > Any reference about that? http://www.postfix.org/TLS_README.html http://www.postfix.org/postconf.5.html#smtpd_tls_wrappermode > [1] - http://www.postfix.org/SASL_README.html -- Offlist mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header
