Hi everyone I would ask you how can I setup postfix to use TLS and non TLS connection on port 587. Below is my current config: submission inet n - - - - smtpd -o syslog_name=postfix/submission -o smtpd_tls_security_level=may -o smtpd_sasl_auth_enable=yes -o smtpd_tls_wrappermode=yes -o smtpd_client_restrictions=permit_sasl_authenticated,reject this should work for me but it doesn't. When for example somebody is trying to send emial via windows live mail and don't "check" option this server require ssl then they got error message "STARTTLS first" any sugestion ? thx in advance
When I connect to port 25 I can see that both startssl and auth plain login method are enabled 250-PIPELINING 250-SIZE 61440000 250-VRFY 250-ETRN 250-STARTTLS 250-AUTH PLAIN LOGIN 250-AUTH=PLAIN LOGIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN but on port 587 I have only startssl 250-PIPELINING 250-SIZE 61440000 250-VRFY 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN how can I enable same on both port Do I need to configure some additional software ?
try to comment out all -o lines after the submission line. Then restart postfix and test again. This should make the submission port equal to the setup of port 25.
Ok I have fixed it. I didn't see that on bottom of master.cf ispconfig3 makes its own submission section with smtpd_tls_security_level=encrypt. Grep command is best friend as always thanx Till for help
