I recently purchased a free class 1 ssl certificate from StartSSL. I am relatively new to this and was hoping for some guidance. I am strictly running a mail server on a basic Amazon EC2 instance and the certificate is registered to the mail sub-domain. I have tried to modify the postfix/main.cf and dovecot.conf files to recognize the SSL certificate and I am able to log into the incoming server through, but the SMTP server fails due to encryption. I am using port 587 and I tried every combination (Auto, SSL, TLS, None). I only changed the smtpd parameters.. Do I need to make changes to the smtp parameters? Any ideas?
