How to update the Validation script for mailing_design.php
Hello, I need to know what file controls the validation for mailing_design.php. I'm having an issue creating a mailing. The "From Email" field will not allow me to use one of the newer TLD's (.media). Could you tell me where to locate the file and what would need to change to allow .media in the email address?
I have included a screen shot that you can see the validation error. I have also tried a .com address and it worked, so something is flagging the .media TLD.
