The code for validating is actually pretty simple, and is very similar to the way you'd perform this particular task using any other OOP language. It will need to be modified to be used in as a form validator, but you can definitely use it as a jumping off point if you're looking to validate email addresses for any form submissions.

So our focus is to ensure that the Mail Message does not throw an exception during a send. But outside of that, if you give bad email address, you don't get an email. Body = email Header "\n" email Body; //send the message Smtp Client smtp = new Smtp Client(Server Address); smtp. So when I try to send an email using this code, I get the exception: "The specified string is not in the form required for an e-mail address." Is there any way to validate the comma delimited email addresses? 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. The following is the basics of the code that will verify that the domain actually exists: There is a lot more you can do, actually trying to connect for example, to verify that the domain will receive the mail. :[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\[\x01-\x09\x0b\x0c\x0e-\x7f]) )\]) I've updated this with a simpler expression (including case insensitivity) in order to hopefully make it a bit clearer.There is a lot to choose from, I, for example, use

This snippet shows you how to easily validate any email using Python's awesome is Valid Email() function. Also, I have no control over the design, or on how that address string comes to my function, I can't add the email validation in the UI, so I am helpless there... I had read somewhere that the only way to validate an email address is to send an email to it, because the regular expressions to validate an email addreess can be surprisingly huge. :[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\[\x01-\x09\x0b\x0c\x0e-\x7f])*")@(? Validating an email means that you're testing whether or not it's a properly formatted email.While this code doesn't actually test if an email is real or fake, it does make sure that the email entered by the user is in a valid email format (a string of a certain length containing characters followed by an @ symbol followed by characters followed by a "." followed by more characters. = None: return True return False if is Valid Email("[email protected]") == True : print "This is a valid email address" else: print "This is not a valid email address" This code can be used in any Python project to check whether or not an email is in the proper format.Select the cells that you want to only allowed to type with email addresses format, and then click Data is the first cell of the column that you want to validate the cells. Then click OK button, now, when you enter texts which are not email addresses format, a warning message box will pop out to remind you, see screenshot: It`s great you can validate straightly in Excel, however, it doesn`t always work properly.
