>> information when people have troubles getting removed from spam databases.
What I gleaned from your extensive list is that very few are contract services with any relationship to the administrator that uses
them.
Actually, that's an authoritative list of all known spam databases (we're one of the two "list keepers" -- Moensted is the other). So every one we are talking about on this list is there, plus many others.
I guess it seems to me that if I'm to trust what their records have, there has to be some obligation on their part to
constantly maintain accurate information, and some mechanism for me (customer) to advise them (vendor) that they have something
wrong and need to fix it, and quickly. There should be some reasonable accountability. Some of them you indicate have whole
providers listed which can't possibly be realistic, and some even have 'spite' listings. How could anyone put the trust of their
enterprise mail in the hands of such operators?
That's a good question. :) I know of one major vendor of mailservers that included default anti-spam settings that included a spam database that does the wholesale blocking of ISPs. If they don't know better, the small guy isn't likely to know better either. That's why it is important to use information from a trustworthy source (such as this list).
Maybe I just don't understand their purpose, but it seems to me that if one is choosing to use an outside resource to provide a
service it's because that resource costs less than doing it iin-house and/or would do a better job than in-house staff...
That is usually the case, in my experience.
... but if there are gross inaccuracies that could cost the company a sale or a customer or reputation it's worthless.
Agreed.
So I guess my question is really about the level of service and support experienced by users of various lists. Since no one else
has chimed in, am I to understand that there is none? Are such services not able to stand up to scrutiny and produce current
evidence to support what they're reporting? If they're not, I'm having a great deal of difficulty in finding the value in their
offerings.
There is very little service, support, and accountability for these lists -- about 98% of which are free (part of the reason for the lack of service/support/accountability). However:
The coming answer might be to just mark X-headers but that seems to just lead me to having to check their results, which doesn't
help at all.
Despite the drawbacks of spam databases, they work amazingly well -- we have included some of them in Declude JunkMail for many years, and find that they work amazingly well as part of a weighted spam system. That way, accidental listings do not cause good mail to be blocked, but spam still gets blocked. It's not 100% perfect, but much closer than relying on a single test.
