Hi, I am trying to replace an old barracuda spam filter application with proxmox mail gateway. To test the setup, mail is being sent to a barracuda application then forwarded to PMG which is then relayed to the mail server. Some mail is being accepted but accompanying it are DNSBL warnings citing blocks due to too many queries. Some other mail is being rejected.
