Exchange attack about

Hello, we are using exchange 2019 cu14 but
It does not prevent crowdsec exchange smtp receive attacks, especially after cu14 has passed.

Has there been a change regarding this? We have installed crowdsec v1.6.1 now, but the situation is the same.

Error logs are as follows and account accounts are locked due to these attacks.

event id: 1035
Inbound authentication failed with error LogonDenied for Receive connector Client Frontend.

Can I ask for your support and information?
