For safety reasons, before-queue content inspection (milter, header/body_checks, etc.) is disabled for automatically-generated email including bounces and postmaster notifications. http://www.postfix.org/postconf.5.html#internal_mail_filter_classes To quote this text: "NOTE: It's generally not safe to enable content inspection of Postfix-generated email messages. The user is warned." For example mail is likely to be discarded when you try to reject an auto-generated message before it is queued. That may be OK for postmaster notices, but rejecting a bounce would breaks email reliability. This is not the complete list of possible problems. I wrote this code almost 10 years ago and I do not have time to redo the analysis that led me to put up warnings like this. Wietse
