I apologize if you've answered this question before. I've read some of the answers I've found in the archives but I don't understand them. What does this message mean? That I failed to send a client certificate CA name? That I failed to receive one? I run openssl s_client -certform gmail.pem -key gmail.key -CAfile cacert.pem -debug -verify 10 -connect smtp.gmail.com:465 I don't see the an argument to send a client certificate CA name in s_client's man page. -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
