Remove your DNS Blacklists? One spam provider says so
Tags :spam SMTP
Our customers have forwarded a blog posting from Mayflower Software that suggests you remove DNS blacklists and then let their software handle everything for spam. While there is one valid point, adding an immeasurable load to your Domino server is not something I suggest. many of the comments on the blog post reflect that fact as well.
I hate to discourage the use of any technique that can stop spam, but I think DNS blacklists should no longer be used by Lotus Domino (IBM Domino) email administrators.
So then jump down to the comments and see what others have to say:
Blacklist can produce false positives but really have positive impact on load. Especially when our SMTP server have limited bandwidth and ratio rejected/accepted messages is high as on our server (we have over 90% rejected connections). Then disabling DNS blacklist does mean that our load on line will be 10 times bigger which is of course unacceptable.
So to our customers that saw this, I write my opinion here. While someone may be blocked accidentally for whatever reason, there is the phone. The load that could come from this on your server is not worth letting a Domino based spam solution solve.
