I know this is a somewhat unusual configuration, but we need SpamAssassin to scan outgoing e-mails. We are doing this so that we can stop spam from being sent by several web-hosting servers. This results in our servers being blacklisted.
I'm having trouble having SpamAssassin treat outgoing mail as potential spam. SA sees the messages coming from only internal networks, so it marks it as "ALL_TRUSTED." I have read these pages: http://wiki.apache.org/spamassassin/FixingAllTrusted and http://wiki.apache.org/spamassassin/TrustPath, but the solutions don't seem to apply to our situation. Basically, all messages passing through SA on this server are from internal addresses, but they still may be spam. Obviously, I don't need to do any RBL tests, but I need to do all the regular content checks. Thanks in advance. --df
