How to remove simple email signature (text) from the inbound emails

[vidhya_mouli]

I have to remove signatures from inbound email before creating incident from it.

I have written the following script in the Inbound Email Action

(function process(/* GlideInboundEmail */ email, /* GlideRecord */ incident, /* Optional: GlideEmailMimeHeader */ mimeHeader) {
    // Get the email body from the email object
    var emailBody = email.getBodyText();

    // Remove common email signature patterns using a regular expression
    emailBody = emailBody.replace(/--\s*\n.*/g, ''); // Replace lines starting with "--" and following text

    // Update the email body in the email object
    email.setBody(emailBody);

})(email, current, email.headers);

And this is my trigger:

The code does not work and I can still see the signature getting attached. Can someone debug this code?

Hi, I do not believe that you can update the email object in this manner and normal process would be to set the current.comments or current.work_notes of the target record directly from your updated variable in your inbound action IE

current.comments = emailBody;

If you want to alter the received sys_email record you would need to use a before insert BR and GlideRecord to lookup and update the sys_email record, but I would not recommend altering a received message in this manner as negates the validity of the message for auditing purposes.
