Hello, As per the Postfix documentation " *smtpd_hard_error_limit (default: normal: 20, overload: 1)*
The maximal number of errors a remote SMTP client is allowed to make without delivering mail. The Postfix SMTP server disconnects when the limit is exceeded. Normally the default limit is 20, but it changes under overload to just 1. With Postfix 2.5 and earlier, the SMTP server always allows up to 20 errors by default " I want to disable this behavior. Means no matter how many errors remote client make, it should not disconnect the connection. I know this is a bad idea. But I still want to do this.
