I've been looking into the same situation actually. I haven't gotten far enough to try yet because of different things I've seen. Domino changes the headers around somewhat, especially the X-headers - converting them to X_ headers. I'm not sure if it even keeps them on a forwarded message (since I had a user forward me a false positive and I had no X_SPAM_* headers from SA).
I'm looking into a method to archive (or log) all messages on the Linux box prior to delivery to Domino. Anyone have an easy way to do that either with SA or sendmail? I thought I had seen a document somewhere allowing mail to be delivered to a SPAM or HAM mailbox as well as the original recipients but can't find it now.

Believe me, I am *totally* open to any suggestions. I believe that this is the least evil way to do it, but I would love to be proven wrong. -- Thomas Cameron, RHCE, CNE, MCSE, MCT Cameron Technical Services, Inc. http://www.camerontech.com/ (512) 454-3200 ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Spamassassin-talk mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/spamassassin-talk ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Spamassassin-talk mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/spamassassin-talk
