>Our infrastructure would look like: >Internet-->[SA]-->[Mailsweeper]-->[SMTP/Lotus Notes gateway]-->Lotus Notes Mail >reader on Client PC >Each bracketed text is a separate server, so SA would be a dedicated relay, with no >local mailboxes, just a passthrough. We have a similar setup - Internet -> Sendmail+MIMEDefang+SA -> Novell GroupWise. No local mailboxes on the sendmail server. We have about 1000 mailboxes with about 20,000 messages per day. FYI - MIMEDefang is a milter (www.roaringpenguin.com/mimedefang), and is GPL'd and OpenSource. It's a great piece of software, just like SA is. >The goal for us is to tag emails (X-Spam-Flag) in a first step and let the Notes >client put tagged msgs > into a separate folder (only saves time, bandwidth and storage are still used). GroupWise has problems looking at the RFC822 header, so we rewrite the subject as SPAM:******* (where the number of asterix (the indomitable gaul :-) ) represents the spam score. We do this using MIMEDefang. Its very easy to write rules (in Outlook, Notes or any other MUA) that look at the subject line, and its visually very obvious to the user when they are looking at their mail. >In a second step we would like to quarantine all detected spam at the SA server level >(thus saving also bandwidth and storage). MD support quarantining for mail with suspicious (non RFC characters), and I imagine it would be quite easy to quarantine messages based on the SPAM score. MD is Perl! Others have already very lucidly responded to your comments about Open Source, so I'll limit myself to mentioning that RoaringPenguin does have a commercial product called Can-IT based on MD+SA that adds per-user preferences, whitelists and blacklists. I have no affiliation with RoaringPenguin - I'm just a very satisfied user of MD.
