Hello, I have configured postfix to check CAfile which contains only Godaddy root certificate as follow
smtp_tls_CAfile = /etc/certs/go-daddy-root-ca.crt my surpirse that still postfix trust the server certificates when email is sent to Yahoo or Gmail.. although the CAfile contains only the godaddy root certificate... i am confused how postix could verify Yahoo and Gmail certificates although only godaddy root certificate existed in the CA file???? So i have removed smtp_tls_CAfile which contained only godaady root certificate from main.cf, now postfix is not trusting Yahoo or Gmail when sending emails to them. This makes me more confused.. Please advise your opinion.. Many thanks Michael Peter
