Email filters conditions

shalini44 · ‎02-23-2016

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

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

Thanks Andrew! I do not see the option to mark it as the 'Correct Answer'. It helped me block this domain.

Hi Andrew,

Even though I had the script for the filters, a incoming email from a domain name "@eePeTraDAaL.h1.AtR.ASia' created a ticket in our system.

I used the following code. I added few more filters to the list. What could have happened?

var filters = [/asia$/i, /top$/i, /xyz$/i, /cricket$/i, /loan$/i, /review$/i];

var answer = true;

var field_to_check = email.origemail;

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

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

{

answer = false;

}

Thanks!
