Java validating email address


26-Nov-2019 18:52

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.

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...

The only way to truly validate the email address is to send an email to that address and request the user to confirm by clicking on a unique link (or entering a confirmation code)Remember, if the user’s intention is to enter an invalid email address, she can do it so easily whether you have the most tough validation or not.

The whole purpose of the Javascript email validation should be to check for any unintentional error (like entering name instead of email).

To verify the validity of an email address simply enter the email address into the box provided and our "validate email address" tool does the rest.

How We Validate Email Addresses Our email validator simply connects to the mail server to ascertain the validity of the email address, verifying whether the email address and username is properly formatted and actually exists.

It used to be that a Reg Ex was the best method for validating email addresses in C#, but with all the new Top Level Domains (TLD's) flying around and new ones being released, this is becoming an increasingly difficult task. To determine whether an email address is valid, pass the email address to the Mail Address.
