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.
