Validating an email address exists
As always, thank so much for this valuable service you all provide. Have a couple of text "email" fields (Personal Email and Work Email, so far) on a Layout.When the data is entered into the field, have it perform a "Calculated Value" within the Auto-Enter tab to check for no more than one "@" symbol and at least one "." (accommodate for a .com, .edu, etc), to change the color of text to red using: If(Pattern Count(Self;"@")1or Pattern Count(Self;".")=0; Text Color(Self; RGB(255;0;0)); Text Color(Self; RGB(0;0;0))) It works beautifully in changing the color of the text to red when the data falls outside these parameters (thanks Discussion)!When you send an email to someone, the message goes to an SMTP server which then looks for the MX (Mail Exchange) records of the email recipient’s domain.For instance, when you send an email to ) is present or not.Using a similar logic, we can verify an email address from the computer without actually sending a test message.Here’s how: Let say that we want to verify if the address [email protected] or not?
Since we have specified the type as MX, our command will extract and list the MX records of the email domain.There's only one real answer to this: a valid email address is one that you can send emails to.There are acknowledged standards for what constitutes a valid email address.To prove just how easy it is, I'm going to walk you through the basics using a simple python script.I'm providing this information as-is and completely for free.
