Mail Consumption Error since 2021/03/15

[andbez]

Using always most recent docker-container for paperless incl. Tika. Since 15th March 2021 Mail-consumption did not work anymore (no changes on my side or eMail-Side, worked 2 Months without any problems before).
Following Error occurs:
[Errno 111] Connection refused : Traceback (most recent call last):

ConnectionRefusedError: [Errno 111] Connection refused

Any Idea?

The error is pretty clear, Paperless can't connect to your mail server. Check your network setup.
