DNS Whitelist support

Is there a chance that DNSWL (DNS Whitelist ... http://www.dnswl.org/) will be implemented in hMailserver.
This would reduce false positives effectively and without much work on serverside.

That looks useful although I wouldn't rely on it 100% What happens if in 6 months time they decide to shut up shop, hmail would have useless code unless it can be made generic enough to be useful with other services. I'm on the fence with this one until I know more about it

Well .. I wouldn't say that if DNSWL shutdowns it would be useless code because you can also use this feature for own whitelists too if it will be implemented in the same way as the DNS blacklists have already been.

And I didn't say that you have to rely 100% on it.
Their recommended usage is:
1.) Skip greylisting for all listed IPs (none - high)
=> All listed hosts are expected to pass greylisting so you are only avoiding delays, not affecting what gets blocked.
2.)Skip blacklisting for all listed IPs (none - high)
=> All listed hosts are known to send legitimate email and should not be blacklisted.
3.) Skip spam filtering for medium and high ranked IPs.
=> These are trusted to send spam rarely enough that they are not worth filtering.

BTW: This is not the only DNS Whitelist available: http://www.spamlinks.net/filter-dnsbl-l ... whitelists

So the chance of having a useless feature after some time is rapidly reduced

I never suggested that you said we rely on it 100% That was my own take on it.

If there are more whitelists out there to choose from then great it has my vote.

So how do you get "whitelisted" in these dnswl ?

You can write a request.
They check at several blacklists (SORBS,...) if your requested IPs have been used for sending spam in the past.

So its a manually updated list

I dont know how "fresh" this list will be once it gets bigger, as it will be almost impossible to maintain.
