One of my network devices seems to have issues with its hostname:
"Unexpected error from e-mail server(state=3): 504 5.5.2 <dazedandconfused>: Helo
command rejected: need fully-qualified hostname."
Appears in my event log of the device when it tries to send logs to my Postfix
gateway server. Is there a filter I can add via main.cf to allow just this
host/IP address without needed the full hostname (which my device has suddenly
not to give :) )
Thanks in advance!

Is this device's IP included in your mynetworks setting? You
should list "permit_mynetworks" before you
"reject_non_fqdn_helo_hostname".
If you don't want to list this device in mynetworks for some
reason, you can use a check_client_access map to whitelist the
client's IP. See the archives if you need examples.
