Dear All, I am running Exim4 4.84.2-1 on Debian Jessie. I was getting error while sending mails to certain domains, but mails were going to domains like gmail, yahoo etc. Then I installed a self certified certificate and a SSL certificate and enabled TLS, assuming issue was with TLS. Still the following errors are appearing when sending mails to certain domains.

Can anyone tell me what is the issue and how to solve this?
