oh,. apologies, i did cut the message down quite a bit :( I understood you were quoting from the spamdiaries website, I apologize to the other listeners (readers?) if it confused the issue.
What you say does seem like a "must do" all right - but putting ARP filters in is actually a reasonable idea.
Atleast it'd trim down the 'problem' to the single customer subnet, I assume that dedicated hosting folks don't just drop machines behind a switch on one big flat subnet? That's probably a naive assumption though :( Perhaps this is clue #12 that that is a 'less than good' option? :)
