You don't. Just make sure that your sendmail box will relay all mail for domain.com (let's assume that's you domain) to your Exchange box. A little side-effect: all messages sent to non-existing addresses in your domain (errors or more likely dictionary spam attacks) will cross your gateway two times (incoming message and bounced error). Quite often, the bounce won't deliver so it will be stuck in the queue of your gateway. Thus its load might be higher than you imagine. > 2. that it sholdn't deliver to the linux box at all, but simply scan and > forward. To achieve this: - make sure that domain.com is _not_ in /etc/mail/local-host-names, so that your gatweway will only deliver mail to [EMAIL PROTECTED] locally - enable the use of the mailertable map in sendmail configuration - in /etc/mail/mailertable, have a line like: domain.com esmtp:exchangebox.domain.com > 3. no mail will be deleted, but will simply have the spam score in the > message header and the Spam in the subject line. then the users of the > exchange server will be able to filter based on Spam Score or the subject > line or whatever. This is pretty much a default SA configuration. I recommend using amavisd-new (http://www.ijs.si/software/amavisd/) to plug SA into sendmail because it interfaces very nicely with sendmail at the Milter interface, has a very well documented setup and configuration file, is fast and stable. You may have to recompile sendmail from source to support Milter, however. It's nice and easy on all popular Unices. > 4. I don't need to scan outgoing mail but i guess that wouldn't hurt as > well. You mean tag spam originating from your domain? Sounds strange... or are you talking about virus scanning here?
