DNSWL - whitelist

[leksand]

I ask you to add DNSBL in the settings - similarly with DNSBL - often blacklist closes good domains and using whitelist can compensate for this.

If you add them to the general DNSBL sites - good domains are blocked:
Jun 20 19:15:09 mail postfix/post screen[22284]: NOQUEUE: reject: RCPT from [108.174.0.201]:51815: 550 5.7.1 Service unavailable; client [108.174.0.201] blocked using list.dnswl.org; from=<m-2kscma73thmg08nshnvpdhu6mezo5fuq3e8h3a7qm6d2kn82uo@bounce.linkedin.com>, to=<mail@mydomain>, proto=ESMTP, helo=<maile-ha.linkedin.com>.

If you run an ip check on dnswl.org:
IP address 108.174.0.201 is whitelisted at dnswl.org with the following details:
DNSWL Id: 3092; Domain: linkedin.com; Sec. Domains: ; Category: Media/Tech Industry (127.0.0.x); Country: US
Please use the dnswl.org Self Service portal for any change requests.
Please remember: dnswl.org is a whitelist, not a blacklist. Please do not contact us requesting "removal from blacklist".

As an option, do an action for DNSBL - not only to reject, but also to be able to send emails to quarantine - to reduce the risk of losing useful emails.

The DNSBL threshold parameter overrides the explicitly specified DNSBL weight via the * character?(psbl.surriel.com *2) or is the priority specified in the address more important?

blocked using list.dnswl.org

From what dnswl.org says - I think it lists IPs which are considered OK - and not the ones who are spamming? :

don't use dnswl.org as DNSBL!

check out the getting started guide in the wiki - orient yourself on the set of DNSBLs there - only if this does not lead to good results add one dnsbl at a time...
