That milter is designed to remove attachments from a message, save them and replace them with a single HTML file pointing to where the attachments have been saved. I was never able to diagnose why until I saw the postfix logs having Unknown commands at the exact same time as the message was received. I started logging these and, lo and behold, coincidence. </span><o:p></o:p></p><p class=MsoNormal><span style='color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span style='color:#1F497D'>Now, I have a milter that comes before my original that just passes on e-mail with unknown commands, but logs when they occur, to whom they were sent, etc. </span><o:p></o:p></p><p class=MsoNormal><span style='color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span style='color:#1F497D'>I’ve just written yet another milter (evolved from the original) that I want to call when the unknown commands are hit.
