Re: 554 5.7.1 Recipient address rejected Policy rejection

iRedAPD plugin 'reject_null_sender' rejects email which has null sender (empty From: address), this is why it rejected this email.

You can disable this plugin in /opt/iredapd/settings.py, or comment out below lines in file /opt/iredapd/plugins/reject_null_sender.py:

    #if not (sender or sasl_username):
    #    logging.debug('Spam (no sender address or sasl_username).')
    #    return SMTP_ACTIONS['reject']

Let me understand. Who rejects the message "mydomain.org" or "somedomain.net" ?
If it is "somedomain.net" who rejects the mail, should I disable that option from "mydomain.org" ?

From that fragment I gues it is the "somedomain.net" who rejects the messages, is it true?

Re: 554 5.7.1 Recipient address rejected Policy rejection

It's easy to forge sender address, helo hostname, and more, so it's hard to say whether it's sent by the real 'somedomain.net'. But if this is not the forged message, then yes, it's sent by 'somedomain.net'.

So what problems to expect after disabling that lines?

Re: 554 5.7.1 Recipient address rejected Policy rejection

No problem. It will bypass MTA notification messages like bounce, non-deliver notification, etc.
