I’ve been informed by one provider that they trigger an ARF report when they see mail move into the spam folder on an IMAP server. So if the built in MUA filters move the mail (say, Apple Mail or the spam filters built into outlook) then that will trigger a report. Other mailbox providers have specifically said they don’t monitor IMAP movement. > There are mailbox providers out there that provide insight into what > percentage of mail from a given source was classified as spam, such as > Microsoft's SNDS program and Google's Postmaster Tools, but I've never > understood those to be feedback loops, per se, as they didn't and don't tell > you which specific messages were judged to be spam by a recipient or other > entity. It’s been a while since I’ve looked at SNDS, but I don’t believe they provide a complaint percentage. What I remember is they provide a % of mail going to spamtraps. Microsoft does provide an ARF feed for mail to their consumer domains. laura -- The Delivery Expert Laura Atkins Word to the Wise la...@wordtothewise.com Delivery hints and commentary: http://wordtothewise.com/blog
