    Hi all,

    Recently built a new system (Ubuntu 14.04LTS) from the Perfect Server guide.

    Everything was working like it should.

    Then followed the Securing with StartSSL guide.

    Then started having issues with EMail. Resolved a problem with receiving emails with both POP3/IMAP and can currently receive both POP3/IMAP with either STARTTLS or SSL/TLS (just some issues that were amended in the guide comments)

    Currently my issue is sending emails from my server with SSL/TLS selected. I can send with STARTTLS, however, when I select SSL/TLS within Thunderbird, it times out.

    In the /var/log/mail.log file, I see:
    May 30 14:26:17 server postfix/smtpd[12320]: connect from unknown[]
    May 30 14:27:36 server postfix/smtpd[12320]: lost connection after  UNKNOWN from unknown[]
    May 30 14:27:36 server postfix/smtpd[12320]: disconnect from unknown[]
    In /etc/postfix/, I do have:
    smtps     inet  n       -       -       -       -       smtpd
      -o syslog_name=postfix/smtps
      -o smtpd_tls_wrappermode=yes
      -o smtpd_sasl_auth_enable=yes
      -o smtpd_client_restrictions=permit_sasl_authenticated,reject
    I'm currently assuming that its a config problem, but at this point, I'm not sure where else to look.
