yep. SA is high overhead. the annoying thing is that besides all the regex work that needs being done, SA is very inefficient in the process. one very annoying observation is the load that persists after the tests complete. Find a slow host, put lots of SA modules on it and watch your spamd log and top, as you check a message... after the score is logged and the message is processed, spamd instances continue using a lot of resources, sometimes much longer than the time taken to process the message. Figuring out what this "post process" resource load is or even which modules cause how much processing load, has been, well, not easy. SA seems the only real choice for an OSS spam filter, but I find the api, poor, and looking at the code tells me resource efficiency was never a consideration either. I'm wanting to write a program that process mail through SA modules, but more efficiently. I'm surprised I've not found one out there already. Maybe scrubber is the answer? http://projects.gasperino.org/scrubber/ (don't know yet...) Back to my own scripts, I'm having a real hard time so much as finding doc (vs example) of the module format. Any tips on what I'm missing are more than welcome. thanks- // George -- George Georgalis, Architect and administrator, Linux services.
