Postfix Question
I'm configuring the new Email server, and i wanna filter the spam.
I decided to configure postfix to filter incoming mail and I do it really with with the command smtpd_helo_restrctions
And it works well, (too well) lots of emails are blocked, but my problem is sine the email doesnt arrive to the email server itself, the sender doesn't receive and email saying why the email is blocked
So a sender will send an email and neither the sender or receiver will receive a note, like the email is lost in oblivion
How can i fix that?

Hm... Too long since I last tinkered around with postfix and its config, but in general you'd have to change it so it doesn't just drop spam without any notice but instead reply to the mail server sending with an error code. That should usually trigger an NDR and notify the sender.
