I have created newsletter with valid emails and test emails. emails are sent successfully and opened, clicked work fine, but bounced and replied do not work.

I have set up mail.catchall.domain to "mydomain.com" and "mail.catchall.alias"  to "catchall" and mail.bounce.domain to "mydomain.com" and "mail.bounce.alias"  to "bounce"
Also, I have setup incoming mail server with bounce@mydomain.com and also the email that was set as outgoing server

Also, I am not testing this in local but a public hosted server. I am using odoo CE V11.0

Any help is much appreciated.
