Constraint / dataPolicy on Email Address

[#1]

So another piece to this puzzle (provided by Support) is the option value for the valid characters in an email address XtkEmail_Characters. I tested this value and this Option value is definitely being used by the mystery validation function to check for valid characters in the email before the write happens.

What they couldn't confirm was how this was applied to the email address (local-part or domain or both). Nor could they confirm what other checks were being performed before the recipient Write was attempted.

OK - I finally have an answer on how ACC determines a valid email. It took way more effort than I expected but we got an answer:

So I am assuming that the first part of this response is the dataPolicy check and the second is a regex against the XtkEmail_Characters option. e.g. something like this

loadLibrary("xtk:shared/nl.js");
loadLibrary("xtk:shared/dataPolicy.js");
var email = "blah232456@gmail.com";
/** 
 *
 * Function to determine if an email is valid for the Adobe Campaign
 * database checks. This process checks using the default email dataPolicy
 * and the option value XtkEmail_Characters.
 * 
 * @param email {string} email address to test
 * @return true(valid) | false(invalid) 
 * 
 **/  
function isValidAdobeEmail( email ) {  
 var patt = "[^@" + getOption('XtkEmail_Characters').replace(/[.*+?\-^${}()|[\]\\]/g, '\\\$&') + "]";
 //logInfo("EmailFunctions.js::isValidAdobeEmail() - Escaped XtkEmail_Characters: " + patt);
 var regex = new RegExp(patt, "g");  
 var testFlag = !regex.test(email);  
 //logInfo("Result of XtkEmail_Characters test: " + ((testFlag)?"valid":"invalid"));
 var dataPolicyResult = !NL.isEmpty(NL.DataPolicy.filter("email", email));  
 //logInfo("Result of dataPolicy email test: " + ((!NL.isEmpty(dataPolicyResult))?"valid":"invalid"));
 return testFlag && dataPolicyResult;  
} 
//Test the email
if( isValidAdobeEmail(email) ) {
  //email address is valid
} else {
  //email is invalid
}

Edit: minimised the code

Hi,

No there is no regex here. The code is matching characters after splitting the string into @ and .

Pseudocode in js would be:

str.split(/[@.]/).filter(function(_){
    return _.match(/^[XtkEmail_Characters as a character class]+$/);
}).length >= 3

Thanks,
