Well, I think it's fine to use RBLs, as long as they're reasonably low weights: they should be a factor in marking spam, but not authoratative. That's the whole point of SpamAssassin. I do think RBLs that merely list "dynamic" addresses are bogus, though. In other news, just recently (this last week), I started getting bounces from all *.rr.com mail. The whole forsaken ISP is rejecting legitimate mail. Now, as it happens, this is a very reason I elided before that I don't want to use my ISP's SMTP relays. If they're willing to drop legitimate mail in the name of "spam prevention" for all of their users' incoming mail, I don't trust them with my mail. I expect this sort of mess from a national ISP, but not from Debian. Incidentally, the national ISP makes less of a mess of it: at least they actually rejected the mail, so I *knew* it had failed; it didn't simply end up in space. (It did apparently come back as a retryable failure, so it took a while to do so.) -- Glenn Maynard
