2. One disadvantages of "zero spam" in a BB/mail-list with world wide members is the high prospect of false positives. The possibility of penalizing a contributor based on their ISP or neighborhood would be counter productive.Can you cite an example where a legitimate contributor's email was blocked based on their ISP or neighborhood where 1) the ISP wasn't voluntarily listed in the PBL, and 2) the "neighborhood" was not a known cesspool of spammers? -Jim P. Of course not! Members of any list would not see a blocked
contributor, and therefor not be in a position to evaluate their
legitimacy. But personally I have been blocked by HotMail, because my
host/VSP with (un-shared) fixed IP is in a "Bad IP block." A
quick review of SpamCop/TALOS spamassassin, and others didn't find
a listing for the /16 block in question. The closest I (or anyone
using email at one of the domains I manage/host) come to spam is
as treasure of a non-profit. I send financial reports to the
other board members ~~ one board member has a HotMail account. So
who knows why my IP was blocked until I objected. It is anecdotal,
yet a citation you requested. But enough clutter. Lou |
