I am using CACert as my signing authority. I have included their root certificate in my main.cf:
smtpd_tls_CAfile = /etc/postfix/ssl/root.crt However, I get this error when it tries to set up a TLS connection: postfix/smtp[5298]: certificate verification failed for xserveoda.aimaudit.com[70.158.194.7]:25: untrusted issuer /O=Root CA/OU=http://www.cacert.org/CN=CA Cert Signing Authority/emailaddress=supp...@cacert.org What is a little confusing to me, and my be the crux of the problem, is which parameter applies to which server, when. Is this error because something is not right on this server or because something is wrong on the initiating server? Both are using CACert as their signing authority. Thanks.
