Hello

Getting a relay error recently following a system replacement.

Looking at this thread: https://forum.iredmail.org/topic12573-a … twork.html

We do NOT have a MYNETWORKS in our iRedAPD /opt/iredapd/settings.py file.   
Yet it was working previously. 

Should this be present?  When & what versions was this required?

Any other details to be aware?

Re: SMTP Relay settings

Is the IPv4 127 required in MYNETWORKS = ['127.0.0.1','10.10.10.0/24']

Any preferred syntax or CIDR for IPv6?

"Yet it was working previously."
    An older Centos host machine was working and got replaced with an Alma Linux 9 machine.



Is the IPv4 127.0.0.1 required in MYNETWORKS = ['127.0.0.1','10.10.10.0/24'] like you had displayed in the other thread or is that just an example illustration?

We have this parameter defined with default value in /opt/iredapd/libs/default_settings.py, you should add this parameter in /opt/iredapd/settings.py if you need to tune its value.

It's mentioned in /opt/iredapd/libs/default_settings.py:

# Trusted IP address or networks.
# Valid formats:
#   - Single IP address: 192.168.1.1
#   - Wildcard IP range: 192.168.1.*, 192.168.*.*, 192.168.*.1
#   - IP subnet: 192.168.1.0/24
MYNETWORKS = []
