Ok. this maybe as simple as I put something wrong in this setting section on Tbird.
Ok to help with this here is my master.cf
smtp inet n - - - - smtpsmtp 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 smtpd_reject_unlisted_recipient=no
I have done the "Copy to Postfix" option in Server Configuration -> Manage SSL Certificates.
When I do netstat -an | grep :465 I get the following
tcp 0 0 0.0.0.0:465 0.0.0.0:* LISTEN tcp6 0 0 :::465 :::* LISTEN
But this is where I am at now. A bit stuck and this is the last thing that I think is holding me back from getting on building the sites.
