My "secret" MX record is:
pds.wsrepro.com. IN MX 10 pds.wsrepro.com.
looks ok:
%dig pds.wsrepro.com. mx
; <<>> DiG 8.3 <<>> pds.wsrepro.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: 1, AUTHORITY: 2, ADDITIONAL: 3 ;; QUERY SECTION: ;; pds.wsrepro.com, type = MX, class = IN

;; ADDITIONAL SECTION: pds.wsrepro.com. 1D IN A 12.148.54.126
But if you're having problems with MS SMTP service, why ask us about that here?
%telnet 12.148.54.126 25
Trying 12.148.54.126...
Connected to pds.wsrepro.com.
Escape character is '^]'.

And, are your mails addressed as [EMAIL PROTECTED] or @wsrepro.com?
because there is no MX for the latter envelope recipient domain:
%dig wsrepro.com. mx
; <<>> DiG 8.3 <<>> wsrepro.com. mx ;; res options: init recurs defnam dnsrch ;; got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 4 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUERY SECTION: ;; wsrepro.com, type = MX, class = IN
absent MX, MTA's will try to send to the A record:
%dig wsrepro.com. a
; <<>> DiG 8.3 <<>> wsrepro.com. a ;; res options: init recurs defnam dnsrch ;; got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 4 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2 ;; QUERY SECTION: ;; wsrepro.com, type = A, class = IN

absent MX records, MTAs will try the A record:
%telnet 12.148.54.123 25 Trying 12.148.54.123... Connected to wsrepro.com. Escape character is '^]'. 220 linux.wsrepro.com ESMTP Postfix
I expect your mails are being received by your machines, just not the machines you expect.
Also, I was referring to the DNS records changes making their way through the Internet
There is no such activity. Your records are immediately available planet-wide as soon as you change them, minus the delays cached records, if any.
