ERROR:

Are you getting error "System address filter excluded email addresses (Illegal semicolon, not in group):"?

SOLUTION:

Take off ";" semicolon character TO "," comma

Sometimes it has some strange characters that you can debug using some convert to ascii ike OnlineStringTools.

In my alzy work i replace using while instead the update all

var gr = new GlideRecord("u_my_own_table");
//gr.addQuery("u_email", "CONTAINS", "\n"); //Enter
//gr.addQuery("u_email", "CONTAINS", " "); //Space
gr.query();
while (gr.next()) {
var tmp = gr.u_email;
var tmp2 = gr.u_email.replaceAll(" ", "").replaceAll(";",",").replaceAll("\n", "");

gs.log(gr.sys_id + " + u_email + "# " + tmp2);

gr.u_email.setValue(tmp2);
gr.update();

}
