Everything seems fine with DNS:

copytronics.com MX preference = 10, mail exchanger = mail.copytronics.com

copytronics.com nameserver = ns3.everydns.net
copytronics.com nameserver = ns.copytronics.com
copytronics.com nameserver = ns2.everydns.net
mail.copytronics.com    internet address = 71.16.126.154
ns2.everydns.net        internet address = 204.152.184.150
ns3.everydns.net        internet address = 208.96.6.134
> copytronics.net
Server:  epdc1.epdom.com
Address:  172.16.2.18

Non-authoritative answer:
copytronics.net MX preference = 10, mail exchanger = mail.copytronics.net

copytronics.net nameserver = ns.copytronics.net
copytronics.net nameserver = ns2.everydns.net
copytronics.net nameserver = ns3.everydns.net
mail.copytronics.net    internet address = 71.16.126.154
ns.copytronics.net      internet address = 66.132.149.237
ns2.everydns.net        internet address = 204.152.184.150
ns3.everydns.net        internet address = 208.96.6.134

I would say your Server is VERY slow at its responces (up to 2 mins a return), maybe you have a performace issue on your mail server?
