Hi all,
I am about to mvoe our postfix MTAs from physical nodes into virtual nodes,
as they're just transmitting and we're not receiving mails on these postfix'es anyways,
I thought it might be not that an overhead, however, everyone seems to accept
the mails from our new VM postfix node except AOL, responding with
an error code [1].
No matter how often I am to read this text, I still don't get what they actually want from me.
We've properly set up DNS (name-to-IP and reverse IP-to-name).
In the logs, I see a message like this:
(delivery temporarily suspended: host
mailin-02.mx.aol.com[64.12.139.193] refused to talk to me: 421 4.7.1 :
Does anyone know what I might have been missing in my config? Well, the config file looks
almost the very same as on the physical nodes, it's just, that the VM doesn't have a direct public IP now.
But the outgoing IP is set up with DNS properly, however.
Many thanks in advance,
Christian Parpart.
