DNS Server resolution issues
Troubleshooting steps to verify DNS is working by following the steps below.
From the gwia server. Do the following nslookup command to see if an DNS name is being resolved to an IP address.
<internet domain name of the receiver>
For example, if having trouble sending email to email@example.com. Use the following nslookup command
If this doesn't resolve back an IP address, this confirms there is something wrong with the DNS resolving IP addresses
Another way to verify this is to create a route.cfg file to force the GWIA to first look at the entries listed here before using the DNS server.
Create a file in the gwia directory and name it route.cfg and in this file type the following.
For Example, in the route.cfg if having problems sending to firstname.lastname@example.org you would type the following:
Save this file and restart the GWIA agent
Now send an email to the specified domain and if it's successful, this will also verify the DNS server is having problems resolving an IP
