Problems with Policyd

[kilburn]

If these are "normal" mail clients, then it means that you're not properly setting them up. Specifically, you are not providing any authentication credentials for the smtp configuration (the exact way on how to do this depends on the mail software you use, but usually there's a "this server requires authentication" checkbox around there that must check). This will solve your problem because authenticated clients doesn't need to pass any policyd-weight nor greylisting filter.
