Getting "handler errors" the log since the update to 0.7

[zb226]

I'm getting quite a few log entries like these:

2023-11-09T15:17:40.094Z smtp: handler error: EOF	
2023-11-09T15:17:52.242Z smtp: handler error: EOF	
2023-11-09T15:17:59.750Z smtp: 220 [MADDY-NAME] ESMTP Service Ready
2023-11-09T15:18:02.027Z smtp: 220 [MADDY-NAME] ESMTP Service Ready
2023-11-09T15:18:02.028Z smtp: handler error: read tcp [MADDY-IP]:1025->[OTHER-IP]:54266: read: connection reset by peer
2023-11-09T15:18:10.097Z smtp: handler error: EOF	
2023-11-09T15:18:22.238Z smtp: handler error: EOF	

...since the update to Maddy 0.7. The instance is running in a big Kubernetes environment and one of the [OTHER-IP]s resolves to a hostname that leads me to believe it is an instance of Blackbox Exporter that is probing Maddy. So I believe the probing was already happening before but I simply didn't get these log messages? Maddy configuration was untouched going from 0.6 to 0.7 and is running with debug yes on global level and io_debug yes for the SMTP endpoint.

Turning off logging (debug no and io_debug no) does not prevent these error messages - which is probably because they don't have a log level associated with them. As I'm not able to stop the source of these probes, is there anything I can do to suppress the messages?

Just wanted to add that I've downgraded Maddy for a short moment to be 100% sure and indeed, the "handler error" messages are not logged with 0.6.2. They start re-appearing when going back to 0.7, independent of any debug setting.
