(During a brief period where I used StartSSL for my SSL certs…)
Had a problem with my mail server. Thunderbird was not accepting the Class 1 cert I got from StartCom. To fix it, I added lines to
/etc/postfix/main.cf. Assume the intermediate CA cert is named “
For dovecot, in /etc/dovecot.conf:
ssl_ca_file = /path/to/certs/sub.class1.server.ca.pem
For postfix, in /etc/postfix/main.cf:
smtpd_tls_CAfile = /path/to/certs/sub.class1.server.ca.pem
Then I restarted both services.
