For our userbase with yahoo/hotmail/aol accouts they hit the spam button more often than delete. Then complain they do not get emails anymore from us, then want discounts on a bill of sale they missed. It is a never ending story.

Yahoo did say "complaints". And it can take a very low level of complaints before a block goes into place - especially for low volume (corporate etc) mailservers. Feedback loops are one cure, and another cure is keeping complaint volumes down. * Do you have an unfiltered NAT gateway pointed to the same IP as your corporate MTA? * Do you have any large spam sources in close proximity to you? Like you are colo'd on a /28 and someone else has a /27 or /26 in the same /24 that's emitting tons of spam (assuming colo). Or you have your mailserver hosted on a dsl pool (even a business class dsl pool) in which case your server is an island of valid mail in a large swamp of virus traffic * Do you have a marketing department that might be slightly overactive? etc etc. srs
