Welcome to the world of pain and frustration that is dealing with Microsoft and Windows live mail spam filtering - yes, they do accept your mail and then silently discard it. I had the same problem. I hammered and hammered with the customer support forms. I could never answer their follow-ups because they wouldn't accept mail from my postmaster address which I used thinking it would give me credibility. My advice here is to sign up for and use a hotmail address in your communications. Anyway, they finally put me on a 2 month 'mitigation' during which my mail was accepted and their spam filters were supposed to retrain, but the day the mitigation ended, the started flaging >10% of my list mail as spam (I had also added SPF records prior to the mitigation). My mail still mostly falls in the 'yellow' (10% to 90% spam) range on 'SNDS' (their Smart Network Data Services reporting service), but it is delivered to either inboxes or spam folders, and all mail is delivered to the inbox of those who whitelist my domain. This in spite of the fact that my complaint rate is essentially zero. -- Mark Sapiro <[EMAIL PROTECTED]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
