Everytime a mail gets delivered to my exchange server the following error gets logged in maillog:
Apr 16 14:49:43 <hostname> postfix/smtp[2146]: certificate verification failed for<exchange-server>[<ipaddress>]:25: untrusted issuer /DC=local/DC=mydomain/CN=mydomain-dc-CA
This is because of my self-signed-certificate I think...
I found a page mentioning the same kind of error but that was concerning GMail and PEM-certificates...
How can I import the root certificate of my domain controller so this error doesn't get logged anymore??
