There are many possible reasons for that. In general, we don't have too much sympathy for people who have configuration problems and then blame us for rejecting their mail. Still, as others have said, the method we're using isn't ideal, and if you can come up with a better one, we're all ears. But you need to come up with the better one first before you'll get too much attention. > I consider myself lucky to have finally gotten the ability to send > email to the lists or to postmaster without it bouncing back.

But is it DNS?

Well, that's your opinion, and certainly one that will gain you little sympathy with the postmaster. One of the goals of the public lists is to allow legitimate users to post messages easily, without being inundated by messages they don't want or having to subscribe and unsubscribe every time. If you disagree with that, that's your prerogative, but to call it "out of touch with reality" is not going to make friends. > (it's extremely ironic that the debate at the time revolved around > this utopian fantasy that people should be able to post to the list > without ever "subscribing"... yet with their current implementation > of arbitrary filtering, they are in fact intentionally blocking > various perfectly innocent users and longtime subscribers from using > the lists, people who have nothing at all to do with "spam") No, this is not a utopian fantasy, it works. I monitor how much mail rejected due to bad DNS is really spam. It's about 99%. If you're talking about other things, it would be nice to hear what they are. >> Calling the filters poor and abritrary is unfair at best, and >> ignorant at worst.

Again, you're not being specific enough.

Well, the person, whose identity you don't reveal, has explained things to you.

How arrogant and > obnoxious that is. And your solution? I see a lot of bitching, but no suggestions about how to improve it. I'm not surprising you're not getting your viewpoint across.
