[openssl-users] openssl s_client

[Walter H.]

Hello,

openssl s_client -connect mailhost:25 -starttls smtp

displays this:

CONNECTED(00000003)
depth=0 OU = Domain Control Validated, CN = ...
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 OU = Domain Control Validated, CN = ...
verify error:num=27:certificate not trusted
verify return:1
depth=0 OU = Domain Control Validated, CN = ...
verify error:num=21:unable to verify the first certificate
verify return:1

the question: is this caused by a config problem on the serverside or on 
the client side (host running openssl)?

Thanks,
Walter
