Postfix | Configure external Blacklists

tynie

Hi,

i´m wondering if it´s possible to configure the external Blacklists like Spamhaus that postfix checks while sending an email. Because some of my customers try sending mails to mailservers which are blocked by uceprotect and i´d like to remove them from my check.

Is that possible?

Individual users can set their own explicit black/white lists as described here. There is also a global regex option if you want to add specific domains.

But if those other customers are being marked as Spammers by Spamhaus, I’d recommend contacting their admins and make them aware. If their domains are valid, they can contact Spamhaus to request removal from the lists.

Also, some info on the RBLs used by Mailcow:
