Converting any message to an attachment - with or without a prepended 'transmittal' explanatory intro, is not limited to triggering on SA score, so yes - Exim can do that first item as well as the rest on your list w/o need of the now-legacy EXIM-SA build [1]. Since SA integration, we have done it a bit differently toward a similar goal: At score (n) we add an 'X-Junk' header with simple SA score - no details. (intended for MUA sorting) At score (n+?) we also prepend 'Suspect' into the Subject Line. At score (n++?) we ALSO route into a 'Suspect' folder instead of the INBOX. Folder is created if non-existent/user deleted [2]. At score (n+++?), we deny outright, and at 'smtp time'. NB: Thresholds are per-user, with a global max as fallback for the unwary. Having a bespoke quarantine folder that one can check 'now and then' seems to be less confusing and less end-user work than leaving the probable spam in the INBOX to be waded through. Especially if attachments might need to be opened... YMMV, of course... Bill [1] How well does that hold up if/as/when the original body MIME-type is mis-identified?
