This has not changed since at least Postfix 1.0, the design of the queue manager is fundamentally based around transport:nexthop pairs. I would expect that it in fact goes back further, but my life with Postfix started with 1.1 snapshots. Content filter support was added less than a year before 1.0 was released in Feb 2001. 20000530 Feature: full content filtering through external software. This uses existing interfaces for sending mail to the external content filter and for injecting it back into Postfix. Details in FILTER_README. Files: pickup/pickup.c, smtpd/smtpd.c, qmgr/qmgr_message.c. -- Viktor.
