Unable to send emails from Linux Centos 7

Hi, 

I m using the sendmail to send out emails on my Linux server.

Attaching the  sendmail.mc here .

I fire the below command to send email but i cant recieve emails to my zoho client mobile app.
  1. echo "hi" | mail mohtashim@digiklug.com
Below is what i see in the maillogs.

I think the problem with my sendmail.mc is that TLS is not enabled. 

I'm not sure if there are any more issues to get this to work.

Can you please help fix my sendmail sendmail.mc configuration so that i m able to send out emails from the linux server?
