Hey,

When trying to use the email inspector in Group Mail I always get a time our (10060) when I do a DNS test even though I know the addresses are fine.

I've gone into my router and forwarded port 53 to my machine and switched off my firewall. Also extended the timeout allowance and no help.

Any ideas? Cheers.

Check the DNS settings on your machine and make sure you can resolve the domain name from a command line "nslookup" command.
If you can then your DNS is setup correctly, this would be the first issue to check.
If DNS is resolving correctly, then check the application settings, there is a DNS timeout option, the default should be 5 seconds, if set to this, try increasing it.  Be carefull not to set it too high, this could causing delays in your applications for every email making the entire application next to useless.

Hey,

Thanks - doing nslookup in command line times out as well.

Any ideas?
Thanks!

check your DNS server ... if it is a good domain name that you are checking then one of two things ...
1. you have a wrong DNS entry, check the IP addresses for the DNS servers and change them if they are wrong
2. you have a problems with the DNS server.

See if you can verify the DNS server addresses ...
In nslookup change the DNS server you are pointing to ...
run nslookup
enter ... server <IP Address of DNS Server>

Now try entering the domain and see if it resolves ... hopefully it is just a mistyped IP address or a bad DNS reference.
If the alternate DNS reference works then change the DNS references.

Do you have control of the DNS servers or are they external servers, handled by your ISP?
if internal, check your frowarding references to make sure they are forwarding external requests to good DNS servers ... again, you can check these with the above referenced nslookup.
