postmaster@proxmox.domain.xx sending emails to admin@domain.tld

[smbuzi]

Hi,

I have deployed Proxmox Mail Gateway, however, there is an email address postmaster@proxmox.domain.xx which keeps sending emails to admin@domain.tld.
How can I block these emails from flooding Mail relay server for the ISP. These emails are also seen passing through the ProxMox Mail Gateway.
Thanks

please share the logs of such a mail, and if possible the mail itself (censor what you have to) - maybe we can then see where this is coming from
