That's a lot of work, how about calling to the dspam server instead?
I'm about to start building a system for ~10,000 users, using dovecot, and was going to use dspam with it... Is this plugin ready for that kind of use? I'll have a global sieve running, cause users won't be able to have their own sieves.
Thanks

I think you might struggle with that many users and the current dspam plugin implementation - it seems a little heavy, but if you run dspam on another machine, then use dspamc from the plugin it may be a little better. Still, I'd be hesitant to run in that size setup, however I think if there was some kind of batch processing worked into the plugin (as I believe was discussed at one stage?) it might work out alright. I imagine that would require keeping an index of the signatures of emails in the folder, then updating the spam status based on the delta between current and previous indexes in a polling period. Currently I find my mail client has a little hiccup whilst it waits for the dspam response which is disconcerting. Also, imagine 1000 users moving say a few messages at once each into a folder, then having to fire up all those dspam threads... not wonderful. With the batch system, you could throttle the number of processes, or any number of other options...
Just idle rambling thoughts...

As Peter noted, I wouldn't use the plugin as-is.
What it should in that kind of setup do is extract the signature and insert it into a database, making sure to take note of all the additional complexities listed on the plugin homepage that come with running dspam out of line.
If you can't make sense of that, I'll reply more in-depth later, don't have much time right now.
