/documentclass(rant) /begin(document) These blacklists may be more trouble than they're worth if they are used indiscriminately. My own ISP checks negative on 31 BLs, positive on 3, and inconclusive on 2. njabl.org, ref'd above, tests negative. dsbl.org tests positive. I went to dsbl.org and found that they tested positive for multi-hop and unconfirmed for single-hop. On the multi-hop, some company in OK, a dsl customer of swbell.net, was the actual open relayer. Obviously, swbell is going to relay his mail, no? So why all the background info? Using this list as an example, I prefer to send a simple compliment, thanks, or maybe an OT personal observation directly rather than to the whole list. (If it were my thread, then a public thank-you would be in order.) If I think someone has erred, I'd rather comment directly in case I'm the doofus (saves embarrassment), or to give the guy a chance to edit his own remarks without being shown up. There are members of the list, though, that automatically bounce or maybe just toss into the bit bucket anything and everything listed by these BLs. I was going to say that any ISP the size of swbell.net would have a lot of innocents, but a search of the last 4200 posts just finds me 8-P I have a whole sh*t pot full of filter defs. Most are pure kill filters. Those that catch globbed names, or IP blocks, I send to my spam directory. It is easy enough to scan the directory and pick out the white hats that get swept up with the usual suspects. I put the good guys where they belong and flush the rest. This gives me the chance to white-list or edit my filter if needed. Don't get me wrong. Anything that will hurt the spammers is a GoodThing (tm). Black lists and such are shotgun approaches and require human intervention to operate nicely. (I wonder how many actual spams are caught, and from which mail servers?) One list member snidely suggested I change ISPs to one more vigilant. Well, if you're in Dallas and you want broadband, there isn't much choice. I suspect that many others also have limited choices to one degree or another. This subject has knotted my shorts from time to time for quite a while and this thread brought out the soap box. This may be less off topic than "The Big Book of Brewing," but I appreciate your indulgence. /end(document) -- gt Everything here could be wrong--Messiah's Handbook--Bach -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
