    Hi, I'm new here !
    I hope someone can help me to fix this issue with relay access denied.

    Postfix server ip is "" and the default gateway is one of the public ip of our ISP, we are using this server to only send out weekly pricelist to customers and everything works fine from subnet. Now I have added a new subnet so the users can send out email from this subnet but we are getting 554 access denied error.
    I have added the new subnet "" in "mynetworks".

    My postconf:

    [[email protected]]/root: postconf -n
