Exclamation User is able to send after changing password on ISPConfig(SASL)


I'm having a huge issue with my ISPConfig installation.

I found out that users who are authenticating on POP3 are able to send email even if their password was changed through the ISPConfig.

if you check the follow log the SASL LOGIN fails but still the email is delivered.

How that can be even possible?
