Try as I might, I can't seem to get iRedMail to accept mail from by log servers...

All I get is

                   The mail system

<pnunn@blah.com.au>: host mail3.blah.com.au[119.17.137.xxx] said: 554
    5.7.1 <pnunn@blah.com.au>: Recipient address rejected: SMTP AUTH is
required for users under this sender domain (in reply to RCPT TO command)

I have a bunch of emails in

/etc/iredapt/settings.py as follows

ALLOWED_LOGIN_MISMATCH_SENDERS = ['pnunn@blah.com.au', 'pnunn@blah2.it', 'pnunn@blah3.com.au'']

ALLOW_FORGED_SENDERS = ['pnunn@blah.com.au', 'pnunn@blah2.com.au','pnunn@blah3.com.au']
   
and yet it still fails.

How do I fix this?
