Hello all
Your mail.quantnet.com and smtp.quantnet.com have nothing to do with your MX records NONE what so ever.
On your MX record you need to point it to an A record for example quantnet.com or you need to create an A record with mail.quantnet.com and point your MX record to it.
June the 8th was IPv6 day : http://www.ipv6day.org/action.php?n=En.IPv6day Where google, yahoo and several other "big" sites double stacked on IPv4 and IPv6 for testing. AND MOST ISP providers for residential lines are not IPv6 ready yet ... so I'm thinking that's what delayed your delivery on that particular day.
your records look fine from what I see
