I setup a new server (OK, several months back) it is an Exim server, the machines sole purpose is to send/receive mail.
I never fully put it into production because I see these strange errors in the logs sometimes: Received TLS cert status response, itself unverifiable It seems to occur when sending mail to some remote hosts.... but not all. A lot of traffic goes out using TLS and there is no issue. When I get this error it occurs before the message it sent. It will actually show the message as being sent using TLS successfully. Here is a little snippet. 2015-11-24 07:09:32 1a17jH-0005wb-FR Received TLS cert status response, itself unverifiable 2015-11-24 07:09:33 1a17jH-0005wb-FR => [email protected] F=< [email protected]> R=ik_r T=r_smtp S=4299 H=mail.safe.com [108.16.186.230] X=TLSv1:AES128-SHA:128 C="250 2.6.0 <[email protected]> [InternalId=66884] Queued mail for delivery" 2015-11-24 07:09:33 1a17jH-0005wb-FR Completed I did some Google searching, the only thing that shows up is Exim source code in github. I checked my other production servers and that error never occurs. Any ideas?
