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: Code: May 30 14:26:17 server postfix/smtpd: connect from unknown[10.10.10.1] May 30 14:27:36 server postfix/smtpd: lost connection after UNKNOWN from unknown[10.10.10.1] May 30 14:27:36 server postfix/smtpd: disconnect from unknown[10.10.10.1] In /etc/postfix/master.cf, I do have: Code: 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. Ideas?
