Yes, Rick, that is correct, but the situation under discussion is that mailscanner passes a partial file to the spamassassin proceess, which in turn passes that partial file to the image analysis plugins, which decide that the image is broken. Upon being passed by spamassassin, the entire, unchanged mail is sent on its way intact by mailscanner. Amavis-New does something similar. Shreds mail into pieces, launches scanners on the pieces. The problem is that the spam scanner (and presumably virus scanner) plugins are being handed partial files. Not a good practice in my view. -- _____________________________________ John Andersen
