Hello Anthony,
Are you sure about that? Is this not your mail server?
Because port 53 (DNS) is not even open:
aphokeer-mac:~ Amreesh$ telnet mail.quantumgroupgh.com 53
Trying 196.10.215.10...
telnet: connect to address 196.10.215.10: Connection refused
telnet: Unable to connect to remote host
Your name servers are:
