AOL declines mails with "421dnsnr" on one of our nodes
- 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 acceptthe mails from our new VM postfix node except AOL, responding withan error code .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[18.104.22.168] 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 looksalmost 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.

Looks good querying from my local resolver in net 18.104.22.168/15.
