Oh, I see your point. What the hell... it's "best" fitted to redhat-list, but is on-topic for any of them really. And we're already here... <grin>


What I dislike (I have stronger words) is the guilt by association
associated with the RBL's and the DUL's or whatever acronym is in use
today.  It is like saying "I saw a (insert ethnic group) man robbing a
7-11.  I think all (same ethnic group) are bad people".

I see your point, but the _theory_ is not there. An RBL is meant to work this way:


 * Someone reports your server as an open relay or spamhaus
 * They test your site
 * They blacklist you
 * You report it fixed
 * They test your site
 * The clear you from the list

In theory, not a bad concept. However, it is in practice that it falls flat on its face sometimes. As I mentioned in another message, sometimes it's not the list that blocks you but other server admins who see patterns and don't have the fine-grained control of some tools to attack it granularly. My partner, for example, went after that particular problem with a large-gauge shotgun, and I still don't know enough about spamassassin to remove her blocks (and I promised not to remove her system until I had a better one).

DUL lists are based on the fact that no one should/does really operate a mail server on a 56Kbps analog dialup line; hence, anyone who does is deliberately skirting their ISP's mail server (to which they already have access, else how do they receive mail?). So large amounts of mail or SMTP connections from dialup points are highly probably spam. Again, not a bad theory, but address ranges change, or people block the wrong ranges, or they block ranges that are too big, or whatever; so again in practice the thing falls down.

Neither type of list is meant to be generic, or to lump people together, or to generalize. However, those things can and do happen. Must improve our anti-spam methods, I guess.
