Hello there,
I am using Zimbra 9 with Proxmox Mail Gateway infront to sort out incoming spam emails.
On Proxmox Mail Gateway I have enabled the option "Verify Receivers" to only allow emails for my accounts - unfortunately this does not work as intented as Zimbra seems to tells Proxmox Mail Gateway that also non-existing accounts are existing.
Proxmox documentation would says:
Where could I check on Zimbra site if those options are set and working?

Proxmox documentation would says:
verifyreceivers: <450 | 550>
Enable receiver verification. The value specifies the numerical reply code when the Postfix SMTP server rejects a recipient address. (postfix options reject_unknown_recipient_domain, reject_unverified_recipient, and unverified_recipient_reject_code)
Where could I check on Zimbra site if those options are set and working?
