The tag would be created by the system administrator and configured in master.cf, in the appropriate smtpd instance that receives the message back from the filter, as is usually done with per-instance configuration. I did read Viktor's email, but the ideas here are in the context of the scheduler protocol being proposed. With the protocol, there would be no need for one-at-a-time delivery and there's no need to duplicate lookup resolution. It would also allow the removal of VERP from Postfix's core, and avoid extra file system load. Andre
