Email filters conditions

[shalini44]

Hi,

We have set up email filters and ignore emails if it comes from certain users which we consider as spam and put them in the junk folder. For this purpose we have setup the conditions using the condition builder. As per the wikis Email Filters - ServiceNow Wiki the value entered in conditions is case-sensitive.

We've started getting many spams where, for example, the domain ends with 'ASIA'   and several variations of it with a mix of upper/lower case letters. So,   we get 'ASIa', 'asIA', 'asiA' etc. How can I ignore the case in the conditions.

Thanks,
Shalini

In order to have a more flexible filter, you will probably need to add custom script that returns true or false based on some regex.

For your ASIA domain example:

var re = /asia$/i; // matches 'asia' at the end of string, case insensitive

return !re.match(email.origemail); // return false if email address matches

Thanks for your reply, Andrew!

If i put the code for regex like below, it should work?

It should, though I am not positive about the field name of the Sender email address (I guessed origemail because that is what it is in other Email Scripts) but also, in these condition scripts, you don't return the answer but set the magic variable "answer" to whether or not you want to allow the email past your filter.

Additionally, you'll probably want to add to this list in the future, so you should write for that eventuality now, as opposed to later.

Try this:

// add to this list as necessary

var filters = [

  /asia$/i

];

var answer = true; // allow email

// this field could be different

var field_to_check = email.origemail;

for (var i = 0; i < filters.length; i++) {

  if (filters[i].match(field_to_check)) {

      // we hit a filter, mark the answer as FALSE

      // to disallow this email from going past

      answer = false;

  }

}

Best of luck,

Andy

That's a great solution! I will try it.

We started getting lot of spams lately and it would great to add them in an array and block.

Thanks!
