Is there a way we can parse and get the value of "X-Original-From" from the header of an email which got forwarded/redirected to Servicenow

[Sn22]

HI All, 

 Our instance has too many forwarded/redirected emails coming in and we want to fetch the "X-Original-From" from the header, is there a way to do that via scripts ?. email.origemail does not give the right sender address hence we want to do it manually.

Did you try using "email.origemail" ?

Hi Vignesh, 

 yes i have tried it, but "email.origemail" also does not give us the right email sender as it goes through 2-3 redirections.

Try this

var str= email.headers;
var mySubString = str.substring(
    str.lastIndexOf("X-Original-Sender:") + 18, 
    str.lastIndexOf("X-Original-Authentication")
);
gs.log("from inbound " +mySubString);
