Even talking SMTP to his mail server mail.jobantech.cd ( 212.39.163.3 ) is
not working. So his problem is a global problem.

His ping response time seems acceptable. So i am  thinking a
problem with  servers config.

Are your servers  behind firewall/proxy server ?


In addition  the result below show that your two NS are on your network.
This is a bad config which should be avoided.
