PMTA setup

To check up on what you wrote -
I see on the PMTA that the config is being written and the fallback dkim+domainkey is uploaded - from there the Mailcarry session stalls or idles.
No signal for pmta reload is in the pmta logs.
If the rest of the domains DKIM's are not uploaded PMTA wont reload

What is see is not happening -
1. nothing is written internaly within the application mysql (yet it keeps the pmta input I gave - can I flush the current cache?)
2. the group PMTA is in the DB

Is there a log output from the application or more precise the pmta mailcarry application script?

I seem to have found the issue. If I enter bounce mailboxs login details in the pmta settings the pmta setup process stalls.
Furthermore if I try to insert(edit what the pmta setup) them (in bounce setup) after running the pmta process (without bounce login details) the application will not save them.

Moving on - I made a complete re-install due to the fact i could not enter bounce details.

Fresh Ubuntu 18.04 with all the bells (PHP7.3)

Circumventing the pmta setup script since this has some issues on the last install - so I'll go manually.

Sending domains - ok
Bounce boxes - Can't save my entered info in the form - I can validate but no save - no php error's - I press save -> top processing bar runs and the form just stays - if I press save and next - same thing happens - I see POST in the log - but that's it..

As in your reply you are looking into this I gather. 

The function that seems to not run -
function onclick(event) {
  submitData(this, this.form, 'POST', '[url]https://[mydomain.com]/bounce[/url]');
}

Can I inject the bounce setting direct to the database (thinking the password is hashed)?

EDIT:
Debug from Chrome browser -

POST https://[mydomain.com]/bounce 500 (Internal Server Error)
send    @    jquery.min.js:2
ajax    @    jquery.min.js:2
submitData    @    custom.js:34
onclick    @    bounces:1

Debug from FF browser -

Source map error: Error: request failed with status 404
Resource URL: https://[mydomain.com]/public/components/jquery/dist/jquery.min.js
Source Map URL: bootstrap-toggle.min.js.map

You are on to something.
So if I don't input password i can save the config - but useless though. Is there a limit to the password? letters, number and special characters - plus length?

Sounds good you are on it (thumbs UP)

Hi again - not sure if this thread is the place for it -but her goes.

If I want to process a list for sending - with let's say 200k subscribers it takes days to process which make Mailcarry useless when working with big lists.

Let me say that the blacklist/suppresion consists of 2mil entries.
