i don't quite understand what you mean, do you want to send a report to a single user? if yes, you can do that with 'pmgqm send --receiver <receiver address>' check the man page or help (e.g. with 'man pmgqm')
in to proxmox mail gateway i have 5 domain
domain 1.com, 2.com, 3.com, 4.com, 5.com
in quarantine i have mail from all of them
i need to send raport from quarantine with e-mail blocked to 1.com and 2.com domain to specific e-mail address
domain 3.com, 4.com and 5.com shouldn't be in this raport
as i said you can only redirect the quarantine report for single users, but you could use the api/cli to script it yourself
(see e.g. https://pmg.proxmox.com/pmg-docs/api-viewer/index.html you can use the api on the cli with pmgsh)
