thanks for your reply. Because of the port conflict we used a different port for Postfix: 2525. So, Postfix is not interfering with Oempro. And MX record of bcnmail.es is set to the server where Oempro is installed (inside a container) and the port mapping has been configured.
Is it possible to run Oempro (v4.14.3) in a container on a server where Postfix (listening on port 2525) is installed? If so, what has to be done that Oempro processes bounces correctly? Right now, our Oempro installation does not process the bounces, i.e. bounced emails show up as Not Bounced and are not unsubscribed from the list.
Example from the logfile:

These three emails are hard-bounced but at Oempro are still subscribed and “Not Bounced”:
Attached two screenshots showing our configuration.
Here is the header of the newsletter we sent out, and where bounces where not detected: https://www.mail-tester.com/test-ypzhsvyz4
Is there a documentation (similar to the article for the old Oempro version) which we can refer to in order to see what we have to do so that bounces are processed?
Thanks a lot for any information you can give us.
