OK, here is the piece that would be of interest,

Now, this shows you are definately relaying through your ISP's mail
server,

  $ dig southeast.rr.com mx

  ; <<>> DiG 8.3 <<>> southeast.rr.com mx 
  ;; res options: init recurs defnam dnsrch
  ;; got answer:
  ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 4
  ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 5, AUTHORITY: 2, ADDITIONAL: 7
  ;; QUERY SECTION:
  ;;      southeast.rr.com, type = MX, class = IN

  ;; ANSWER SECTION:
  southeast.rr.com.       1H IN MX        100 mail6.southeast.rr.com.
  .
  .
  .
  ;; ADDITIONAL SECTION:
  mail6.southeast.rr.com.  1H IN A  24.93.67.53

However, this might be trouble,

  $ dig Mail6.sc.rr.com

  ; <<>> DiG 8.3 <<>> Mail6.sc.rr.com 
  ;; res options: init recurs defnam dnsrch
  ;; got answer:
  ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 4
  ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2
  ;; QUERY SECTION:
  ;;      Mail6.sc.rr.com, type = A, class = IN

  ;; ANSWER SECTION:
  Mail6.sc.rr.com.        23h56m20s IN A  24.93.67.181
  .
  .
  .

Your mailserver seems to be using a name, Mail6.sc.rr.com, that does
not agree with the IP, 24.93.67.53 (or vice versa).

Still, it's weird. You might want to consider a mail to the
'postmaster's at both ISPs. They should really work this out. It looks
like you are doing everything right.
