Once in a while, upon submission, users will get and error message instead of a success page. For us, the errors are typically notification or confirmation email errors (bad smtp config, using a semi-colon instead of a comma between multiple email addresses, incorrectly formatted emails, etc), that result in a php or sql error message, but the submission (and often the confirmation to the user) When users see this, they tend to resubmit the form multiple times before finally contacting someone. This is especially problematic when payment is involved.
It would be great if instead of the generic error message, a page could be displayed that simple says something like "There was a system error with your submission, please contact us before submitting the form again."
