Hi Everyone:

I need your help solving a problem(I think it's hard so I'm assigning it 500 points).  

I went into a customer site, and found no firewall was in place.  So, I installed a SonicWall PRO 3060, and correctly configured the appliance.  I set all of the pc's up for DHCP and the servers I setup with a static IP address.  

Unfortunately, now I cannot receive inbound emails.  I can send email out, and can receive intracompany emails, but cannot receive emails outside of the office.  

EEK PLEASE GIVE ME SOME POINTERS! =)

Are you using an Exchange Server or some other type of mail server?
Have you mapped any ports through the firewall?
Are collecting mail for a whole domain name?

Unless you are using your ISP's pop3 email for collection you will need to map port 25 to your internal mail servers IP  address.  

Good Luck,
Matt

I am using Exchange Server 2003.  I have mapped the ports through the firewall.

What IP does the mx record for the domain name point to?
Try to telnet to port 25 on the server internally.  Then try to telnet to port 25 externally.  Let me know if you need help with this.

Thanks,
Matt

When you email out, is the email actually being sent to an address that you can check for?

Telnet to 25 doesn't seem to work on that IP : 67.154.110.162 which means that either your firewall is blocking the request or the port 25 mapping is wrong.  In either case, no one from the outside can contact your email server.

Was the email server working before you setup the firewall?

I'm with LimeSMJ I can't telnet to port 25 at that address.  The port mapping on the sonicwall must be seup incorrectly.  Have you tried to telnet to it internally?  Do this.

Start->Run
type cmd hit enter
then type
telnet "internal ip of exchange server" 25 "then hit enter"

If you get any response from this let us know.

Good Luck, Matt

Definitely a sonicwall port mapping problem.
If you are using the standard OS, then make sure:
one-to-one NAT is enabled
you have the internal IP of the server linked to 67.154.110.162
you have a rule as follows:
allow: source WAN * : destination LAN (IP of server) : service SMTP

then you should be able to telnet from outside and it should work.
