Hi, I'm following the howto of installing postfix on debian and have nearly reached the end. At the moment, i can receive email using pop3/pop3s/imap/imaps and send mail using only smpt. I run a nmap and notice that port 110, 995, 143, 993 and 25 were open, but there's no open port 465 needed for smpts. How was that, is port 465 intended to open in the howto? or how to open that port so that i can send email securely using smpts. thanks alot!
ah yes, that's great. Thanks so much! My mistake is that just uncommented the first line only: Code: #smtps inet n - - - - smtpd this makes postfix listen on port 465 yet that's not enough, i couldn't configure my email client to send email thru port 465 (encryption type is ssl) only when the next line is removed comment Code: # -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes i can send message wrapped by ssl by the way, if i just uncommend the first line, i could still send message under port 25 with tls. So what's the difference btw ssl and tls, can u explain it for me? thank you edge, and you, falko, for your outstanding howto!
