Hi there,

I'm wondering how to set up DNSBL. The factory config seems to be rather empty:

Also, there is not much information what to put in there in the docs:

I thought that PMG already takes care of defining basic settings so that one is "ready to go" with the default. Is that not the case for DNSBL?
If not, where can I find helpful documentation what to put in there (please don't refer to the Postfix manpages. There are not helpful IMHO).

Many thanks in advance!
 
hi,
proxmox cant choose for you, because it is 3rd party provider and every provider has some terms (free use, access code, public mirror...)
for example for spamhaus.


MY SITES
filter after =, and weight after * (postscreen_dnsbl_threshold). usage:

Code:
zen.spamhaus.org=127.0.0.[2..11]*3                                                                                                                                                                                                                                       
bl.spamcop.net*3
dnsbl.sorbs.net*2
b.barracudacentral.org*1
list.dnswl.org=127.[0..255].[0..255].0*-2
list.dnswl.org=127.0.[0..255].[1..3]*-5
