There are also those that let fill in the appropriate information and can simulate an SPF check from anyone and from anywhere.The Tools page has information on specific test tools known to be available. Now the problem is that, in case of multiple comma delimited addresses, one or two of them might be of the wrong email address format. Send(mail); Now the "to Address" string that my function recieves might contain a single address, or it might have many, comma delimited addresses. String email = "[email protected];foo#bar.com"; String expression = @"\w ([- .']\w )*@\w ([-.]\w )*\.\w ([-.]\w )*"; Regex regex = new Regex(expression); String emails = email.When you play around with the function, you’ll notice that the validation function is only called when the focus leaves the field, so you have to click outside of the field to actually make that error message pop up.
One of the questions I get asked again and again is how to validate a field value in an Acro Form with a custom validation script.
My problem is that the email will not be delivered to ALL the addresses in the comma delimited string, even though only SOME of the addresses are of the wrong format.
