Hi

I have an odd error in yesterdays mail.log. This is a one off and cannot be replicated

Where/what to start looking for something  that caused this. 'OK'

Somewhere in your smtpd_*_restrictions lists there's an error. Most likely a typo in an access map of some sort.

Impossible for anyone here to even guess which one without the debugging info suggested here:
