    Default How do I disable the "hello hostname" valid for one specific domain?

    Hello Guys,

    How do I disable the "hello hostname" valid for one specific domain?

    I am having trouble receiving emails from a recipient due to error.

    I can only get it , if i put the ip of the sender on "My networks", which ends up opening the relay.

    Sorry for the english.

    The problem is caused by your server responding with an incorrect 'helo', you need to fix that. The 'helo' should match the DNS records/reverse DNS/primary domain name for your server - once you fix that you should have no problems and it doesn't matter how many domains you have on the server. You also appear to have two MX records for your domain that have a priority of "0" (zero), that's also not a good idea as trying to connect to your server will sometimes pick the wrong IP address and it times out trying to connect to the IP 177.69.142.155 - I'd suggest you fix that as well.
