Exchange not receive email from outside

For some reason our exchange server is not getting email from outside of our company. I thought it was always working but maybe i was wrong. All the email still go to the pop server. i dont know if something is wrong on the DNS or firewall set up but it is not getting email though...please help

well here is our DNS
ateraldata.com      209.132.227.61
      mail.lateraldata.com       66.226.27.250
      smtp.lateraldata.com       198.66.93.70
      smtpmail.lateraldata.com       198.66.93.70
      owamail.lateraldata.com       smtp.lateraldata.com.
      lateraldata.com       smtp.lateraldata.com. (20)
      pop.lateraldata.com       smtp.lateraldata.com.
      ftp.lateraldata.com       198.66.93.78
      *.lateraldata.com       209.132.227.61
      lateraldata.com       mail.lateraldata.com. (40)

and we just remove the mail.lateraldata.com MX record because we want all the email to go to the exchange server.. this is an offsite POP mail server but all a sudden we are not getting email anymore. so apparently the email have been going to the pop server and then to us...we have 2 accounts for each users..one hook up the the exchange and one popping email from the mail.lateraldata.com...and the strange thing it that it never rebounce back to the senders?

You can check yourself.

It is connecting to smtp...

However it looks like you have a PIX. Disable the Fixup SMTP option in the PIX, as it can cause you problems.
