ccsi.com has an MX record that points to backup.ccsi.com (sounds messed up) as well as an A record. mail.ccsi.com has an A record and no MX. What address are you sending to? If it's [log in to unmask], then there might be a problem if the MX (backup.ccsi.com) is down, or not forwarding mail to the proper server for ccsi.com. I tried to connect to backup.ccsi.com, and it timed out. Most MTAs will deliver to the A record if there is no MX record, but in this case, there is an MX that is not responding. Most MTAs do not try an A record if there is an MX that fails. mail.ccsi.com did answer on port 25. Sounds like they need a DNS Dope Slap.
