I have changed it a bit but the problem remains.

document.addEventListener('DOMContentLoaded', function () {

const optgroups1 = document.getElementById('pos_select').getElementsByTagName('optgroup');
let sel = document.getElementById('candidate_functionalarea_id');
sel.addEventListener("change", function () {
let evnt = document.getElementById("candidate_functionalarea_id");
let options = dyndrop(optgroups1, evnt);
document.getElementById('candidate_positioncategory_id').innerHTML = options;
});

const optgroups2 = document.getElementById('tag_select').getElementsByTagName('optgroup');
let sel2 = document.getElementById('candidate_function_id');
sel2.addEventListener("change", function () {
let evnt2 = document.getElementById("candidate_functionalarea_id");
let options = dyndrop(optgroups2, evnt2);
document.getElementById('candidate_positioncategory_id').innerHTML = options;
});

function dyndrop(optgroups, evnt) {
let option_text = evnt.options[evnt.selectedIndex].text;
let option_id = evnt.options[evnt.selectedIndex].value;
let options;
for (let i = 0; i < optgroups.length; i++) {
if (optgroups[i].label == option_text) {
options = optgroups[i].innerHTML;
}
}
return options;
};
});

I have 2 dynamic dropdowns that are placed on the end of a form (simple_form). The select works only once. If I select once more optgroups1 and optgroups2 is empty. On load both variables are set as expected.

const optgroups1 = document.getElementById('pos_select').getElementsByTagName('optgroup');
let sel = document.getElementById('candidate_functionalarea_id');
sel.addEventListener("change", function () {
let evnt = document.getElementById("candidate_functionalarea_id");
let options = dyndrop(optgroups1, evnt);
document.getElementById('candidate_positioncategory_id').innerHTML = options;
});

const optgroups2 = document.getElementById('tag_select').getElementsByTagName('optgroup');
let sel2 = document.getElementById('candidate_function_id');
sel2.addEventListener("change", function () {
let evnt2 = document.getElementById("candidate_functionalarea_id");
let options = dyndrop(optgroups2, evnt2);
document.getElementById('candidate_positioncategory_id').innerHTML = options;
});

function dyndrop(optgroups, evnt) {
let option_text = evnt.options[evnt.selectedIndex].text;
let option_id = evnt.options[evnt.selectedIndex].value;
let options;
for (let i = 0; i < optgroups.length; i++) {
if (optgroups[i].label == option_text) {
options = optgroups[i].innerHTML;
}
}
return options;
};

With ps ax I get the following list of processes. How could I identify the process?

I have a Rails application that runs on an Ubuntu server and sends emails through an external SMTP server. Now I was informed by my provider that the email password of the SMTP server was hacked and that spam mails are sent via the SMTP server.

I have now changed all passwords, the access password to my provider and the email password of the domain. I changed the root password on my Ubuntu server and closed all postfix ports on the firewall. The server is now only accessible via ports 80 and 443.

And still spam mails are still sent via the SMTP server. Where could I still have a security gap?
