Interesting issue I ran into while setting up the contact forms on a few of my websites after setting up this new server of mine. Sometimes the form would work and it would send the email as expected after form submission, but most of the time it would error "Error in processing. The server response was: Greylisted, please try again in XXX seconds".
I triple checked all my settings in the program, using ASP.NET/C# I know the settings quite well and everything appeared like it should be working. Well I kept digging, took me a couple days when I finally uncovered a setting. Don't you love when you spend a crazy amount of time on something only to find it is a stupid box that needs to be checked?
My e-mail is controlled by SmarterMail 7.6, and there is a setting in there to disable Greylisting. So log in to SmarterMail and click settings:
Then go to the "User" tab, and make sure "Disable Greylisting" box is checked. Save and viola... your issue should be solved.
So there you have it... another silly and easy issue, on to the next problem!
