Hello

Is it possible to give the ability to the user to put a received mail into a blacklist ? The received mail is a mail that has not been detected as SPAM as suspicious and the user wants to avoid to receive the email again in future.

I've set up sync with AD and I thought I could use this config for SSO so that a user can be logged in in Proxmox mailgateway with his windows credentials but that seems not to be the case.

If we set up SSO over OIDC, can we than provide a way that a user can put a received mail into blacklist, maybe over API call or something else ?
