    I am using PMX MG for both incoming and outgoing emails. Emails are flowing fine, except the Deferred Mail list is full of items saying
    Sender address rejected: Domain not found (in reply to RCPT TO command)

    The error msg is only for all notification emails the gateway is trying to send to the admin email. The sender address shows, instead of Nobody is getting these SPAM notifications or any other notifications that the gateway is trying to send out. What do I need to configure further to start receiving this notification emails?

    I have the exact same Problem. My workaround was to setup the subdomain as Maildomain. So my Server knows the sender. But I'm not relaying it.

    Would be nice, if that can be changed.
    additional info: Its only the Proxmox Status Report that gets send from postmaster@hostname.hostdomain.tld
