    I'm triyng to use SMTP via the submission(587) port. I see postfix correctly listening to 587, I can telnet to that in LAN and from outside, but when I try configuring an email client it says "Connection timed out". If I use port 25 or 465 everything works perfectly.
    This is what I see in logs:
    Code:
    Nov  2 09:19:34 demo postfix/smtps/smtpd[864]: connect from unknown[2000::ff8d]
    Nov  2 09:21:14 demo postfix/smtps/smtpd[864]: SSL_accept error from unknown[2000::ff8d]: lost connection
    Nov  2 09:21:14 demo postfix/smtps/smtpd[864]: lost connection after CONNECT from unknown[2000::ff8d]
    Nov  2 09:21:14 demo postfix/smtps/smtpd[864]: disconnect from unknown[2000::ff8d]
    
    (it happens in ipv4 as well)

    yes it is, netstat shows port 587 open:

    Code:
    smtp      inet  n       -       -       -       -       smtpd
    #smtp      inet  n       -       -       -       1       postscreen
    #smtpd     pass  -       -       -       -       -       smtpd
    #dnsblog   unix  -       -       -       -       0       dnsblog
    #tlsproxy  unix  -       -       -       -       0       tlsproxy
    submission inet n       -       -       -       -       smtpd
      -o syslog_name=postfix/submission
      -o smtpd_tls_security_level=encrypt
      -o smtpd_sasl_auth_enable=yes

    #  -o milter_macro_daemon_name=ORIGINATING
    smtps     inet  n       -       -       -       -       smtpd
