Is there any way to check the validity of an email address by doing something similar to the ping of a url except that I am checking for the existence of an email address?
Maybe an email validation through telnet or something.
The objective is to check and see if I have a valid email address by trying to reference the email address. When a person updates or stores an email address, I want to check to make sure the address is valid by actually having my code reference it and get a response. That way I know I am not storing junk email addresses.
I do have the code to check for the general syntax of an email, but that does not ensure the email address is valid. It only checks for correct syntax.
