HI  guys

I'm not sure if this is the right place to ask this question or not. If
not, please let me know where I should ask this question.

Due to an ADSL issue I had to factory reset my ADSL MODEM (DLink 604+).
This has now caused an issue with incoming mail (our Exchange mail
server ) which  sits behind this router on because the
port redirections we blown away by the reset.

I have set up Port Redirection to for ports 25, 80, 110,
143, 220, 3389 - all TCP.

The mail server is sending mail out and receiving mail sent to its
domain but I cannot receive any mail from the outside world.  For
example, I have tried to send myself mail from a Hotmail account but it
gets rejected (Delivery to the folowing recipients has been delayed).

The router has a static IP - none of that has been changed so it should
be just a matter of letting the traffic through ot the server. pings okay on the network.

I am a bit of a novice at this.  What have I missed?  What can I test?
