Anyone using SMTP to send mail?
I have an application using the SMTP services.
My application deploys onto Windows XP embedded which is basically XP pro.
I have some problems when the SMTP server will send a request to the DNS
server to resolve a URL.
The problem is that if the DNS does not respond on the first try, it will
give up.
The request is UDP so it should retry.
When I do a test using the browser and the DNS request does not get a
response, it retries in about 1 second if no response is given.
I would expect the DNS client to react in the same way for an HTTP as well
as SMTP but it does not seem to do so.
I am debugging this by sniffing the ethernet line.
