System Status Checks: Mail Filters (Sieve/dovecot) is running but is not publicly accessible at :4190

Hi,

How would I fix this error message:

:heavy_multiplication_x: Mail Filters (Sieve/dovecot) is running but is not publicly accessible at my IP:4190.

Thanks,

Hi,
Add the port to your port forwarding setup.

Iā€™m having the exact same issue in my web interface. However, MAIB seems to be working fine so far. For my ports, I have port 4190/tcp forwarded from my router to my server. UFW in my server shows that 4190 is open. Is there any other way I can start debugging this?

Is this the only port MiaB is complaining about?
