    Mail Filter Disables Quarantine

    I setup a new Mail Filter Rule to quarantine, however, when I enable the rule, it seems like the quarantine breaks. Everything starts coming through. Not sure how to proceed in diagnosing the issue. The current Spam Level 3 works fine, just not when I flip over to my Spam Level 4.

    Zentyal Mail Server + Proxmox Mail Gateway, worth it or redundant?

    Hello, I love Proxmox VE and now I'm deploying Zentyal as a mail server, so I wonder if it is worth it to add Proxmox Mail Gateway to my infrastructure. Since Zentyal already includes Sieve, Amavis, ClamAV and SpamAssasin, will I get any benefit with Proxmox Mail Gateway or would that be...
