> 1. Can SA work well as an opt-in/opt-out solution? I first encountered SA on The Well (http://www.well.com) and it was offered as an opt-out service. A web page is provided to opt out and to fine-tune settings. The only thing I've done is to change the subject tag to include the score. I can then set my spam folder to sort on subject and show only unread messages, so any false postives (ie. low scores) will cluster near the top. > 2. What kind of false positive % should I expect? My Well account gets about 100 messages a day, and when I used it for a lot of mailing lists, I'd get about a 1-2% FP rate. OTOH, it misses about 2-3 spams a day. > 3.

Since I liked SA so much with my Well account, I installed it on my own mail servers (office and home), but without any custom configuration ability for the users. The only maintenance I've done is upgrades, which amount to recompiling the source RPM and installing it. > 4. How well does it perform at large sites? (We process around > 5-700,000 emails a day) Recent versions were optimized to process a message pretty quick, but that's a LOT of mail (almost 10 messages per second). Is that distributed over multiple servers or CPU's? (My company site is only maybe 500 messages/day.) > 5. What MTA do you recommend? I'm using sendmail/procmail on Red Hat, and SA gets called from procmail as a filter. Others run SA as a sendmail milter. I'd expect you to run spamc/spamd to avoid the Perl process startup costs for each message. It's pretty easy to set up. > The design I'm looking at is a gateway solution that our users can > opt-in to.

Has anyone here implemented a similar > design to this? I'd be interested in hearing of web-based packages to allow users to customize their personal setups. This is probably complicated in your situation by the need to work with users who don't have true Unix accounts, so SA needs a way to find per-user configuration.
