Greetings Postfix users,
I am building a postfix system to act as our SMTP relay at the network
edge. The system will be used by servers and applications to send email
both internal to our network and external as needed.
I have a postfix system specifying the mynetworks parameter noted below and
checking the hash via "postmap -s hash:/etc/postfix/network_table" returns
a list of ips.
However when I check the config after restarting or reloading postfix the
parameter does not seem to be updated when reviewing postconf -d.
Doing a quick command line check to send email on the system with postfix
mail is sent without issue however sending it from my desktop through that
relay server with the noted command it is failing with connection rejected
which is why I believe the mynetworks parameter is the issue.
All help and suggestions are appreciated.
Thanks
Blake
