We upgraded from W2k3 SBS to Windows Server 2003 R2. Our email was being house by a third party via pop3. We migrated over to exchanged made all the the configuations and now we can send and recieved email internal and send out external but we can not recieved from the outside world. We have a just replaced out Cisco 871 with the SonicWall TZ190. I went to MXToolbox.com and it show the MX record pointing to our static IP but when I ran a dianostic the only this display was on the Banner it said Argument 'Length' must be greater or equal to zero.
