I should say that they do offer spam filtering but I found it too inflexible for my taste (I could only adjust SA's trigger score for my account) so I leave their filtering off and run my own copy of SA. I also added a custom scanner to logwatch to calculate spam percentages. Is there any way that greylisting can be implemented that would allow users to opt in/out of it on a per-account basis?
