[SOLVED] DNSBL Threshold

[Pavel Hruška]

Hello there, please can anybody explain me DNSBL Threshold config value in Mail Proxy/Options? Does it mean that at least X DNSBL hits must be triggered simultaneously to get message rejected?

I would appreciate better description for some config values in documentation, this one is not even documented.

Thank you.

The option 'DNSBL Threshold' in the GUI ends up as dnsbl_threshold in '/etc/pmg/pmg.conf' (in the section mail).
It is documented (while not in the screenshot) under 4.5.4 in https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#_mail_proxy_configuration

I hope this helps!

You need to have multiple DNSBL sites configured before considering changing the value above 1. The threshold value is the score that a message needs to fail the DNSBL check and be rejected. By default each site that the message fails the check increments the score value by 1.

You can give certain site a higher weight with a *number
For example .com has a higher weight of 2 over .net and .org filters:
example.com*2, example.net, example.org

Yes, thank you. For some reason I was not able to get it last time I've checked the docs, now it's clear.
