My ISP implemented grey-listing over a year ago. When they did, my overall spam rate immediately dropped from 80% of my mail stream to under 10%. Currently spam is running at less than 5%. As a result my SA subsystem is mostly trapping spam sent over less-common channels, e.g. mailing lists and an ISP-provided address I no longer use. Having to handle a stream of large spam messages can't be improving the throughput and disk usage of your hosting site's mail server either, so its worth pointing that out to them. They may be more amenable to introducing grey-listing than you realise. Martin
