And if you mix inbound email (much dirtier than outbound email even if you run a secure shop) into a mail stream that includes email sent out by your clients, you potentially have random botnet spam, spam from sbl listed spammers etc (in other words, a lot of "block on sight" stuff) leaking through your IP, the same IP that a bunch of your other customers use to mail out to their aunt mary on yahoo. The numbers from that one .forward are enough to screw up the rest of your numbers, a 5% or less complaint rate on email from your IP (and believe me, if your user is jackass enough to click report spam on email that comes through his .forward the complaints can go up real high) .. is enough to get your IP blocked. Dealing with tier 1 support anywhere (not the least of where is yahoo) is always a pain. Which is why what I am suggesting is avoidance and prevention rather than going around alternatively begging yahoo to fix something or accusing them on nanog of being arrogant. --srs
