Sonicwall TZ190 SMTP Help
Hey!
I just upgraded my network's (Windows Small Business Server 2003 with about 20 clients connected) firewall from a Sonicwall Soho3 to a Sonicwall TZ 190. I threw in all the configurations from the last firewall and everything seems to be working fine except i can't send e-mails! The network uses Exchange with Outlook 2003. I can receive them easily but when i try to send one i get the following error:
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. <mycompany.com #5.5.0 smtp;550 relaying mail to gmail.com is not allowed>
Now i figure it might be a DNS problem and i forgot to add a setting. There's just a billion more settings in the TZ then there was in the Soho. I've gone into the system manager > SMTP server and checked to make sure all the authentication settings are right. I know it has to do something with the firewall i just can't put my finger on the setting. If i plug the Soho3 back in everything works fine(incoming and outoing). Help is much appreciated!
Thanks!

I've double checked all the policies and i'm still getting the error.

<myserver.com #5.5.0 smtp;550 relaying mail to gmail.com is not allowed>
I've tried looking through the help center on the microsoft site and still no success. I've even tried calling their tech help (sonicwall's) but on the weekend they take forever to transfer and don't seem to be much help either.

I just got off the phone with the Sonicwall tech and they said its probably a setting that our isp uses. We use Cox Cable for our ISP and i checked the smtp connector on our exchange server and it has smarthost.coxmail.com as the forward. Is there some setting in the firewall that i need to change to convey this?
ASKER
I just called Cox and they added our ip to their relay in the database but i'm sure that isn't going to make a difference considering we could send email before we installed the new firewall. And that's pretty much the only advice they can give us...

I've tried everything so far and nothing seems to work. Anyone else have any light on the situation? I know it has to be just one setting.

I've turned on smtp logging to see if that can help shine the light. here are a couple of errors.
This is an SMTP protocol error log for virtual server ID 1, connection #2. The remote host "68.99.120.5", responded to the SMTP command "rcpt" with "550 relaying mail to gmail.com is not allowed ". The full command sent was "RCPT TO:<aegis@gmail.com> ". This will probably cause the connection to fail.
