We pulled out an email log to verify the TLS Version used and we could see the "TLS_Cipher" & "TLS_Verified". Most of the transactions happened via the TLS1.2 except 3 or 4 which showed as ":" and all the transactions have TLS_Verified as "unverified". Will there be any impact because of the certificate not being verified? What are the steps we need to follow to get it verified. Request your inputs on this.

@Vinod Mummareddy Sincere apologies for missing your post ... From what I saw in your log, the messages delivered via TLS 1.0 were all delivered to hosts with IP address in 186.90.28.* ... it is possible that some of the MTAs for your domain support TLS1.1 and higher and some do not. You should speak with your Mail team. Please see the direct message I sent you as well ...
