I don't understand the logic behind blocking the domain either. I wasn't here for this history, so I don't know the problems that the yahoo domain may have caused in the past - but I really don't understand how blocking the yahoo domain helps reduce spam. This message is the only one I have seen in the thread that seems to give any technical info as to how this blocking helps reduce spam... http://archives.mn-linux.org/pipermail/tclug-list/2001-June/027635.html And even that doesn't really make it clear to me how bots are sending mail to a members only list through yahoo accounts. Since this is members only - are you saying, that the bots (which apparently only use yahoo accounts) are capable of signing up to the list, and then sending spam from their valid, registered accounts? If the bots are this smart, why don't they use other addresses beside yahoo? Maybe the answers are already obvious to the pro sys admins on the list. I think this question needs more real facts than poll results. Why not do a 1 month (or less, if a spam problem develops) test run to see if allowing yahoo accounts is still a real problem. Then take a poll - with real facts backing up the choices of the poll. Arbitrary decisions like this seem rather draconian when people (like me) don't know the history or the reasoning behind the decisions that were made years ago.
