Re: SMTP troubles (AGAIN!)

Can you ping the DNS servers?  If not, then that's the
problem.  They're not the right ones.  If so, then
something else is fishy.

You shouldn't need an IPL to change those values.  Simply
changing them it should take affect right away.

If you can ping google's IP, then you have connectivity.
 That's a good start.  :)  If you can't ping the domain
name and at least get a resolution to an IP, then there are
still DNS issues that need to be worked out.

Do you have a network admin that can tell you what DNS
server(s) to specify?
