I investigated this in 2002, and was unable to find an easy way to make
Postfix do this. In theory, all that is necessary is to drop files
into Postfix's "maildrop" directory and then signal the queue runner.
However, the maildrop directory contains files in a Postfix internal
format rather than in RFC822 format.
The approach to take would be to abstract the routines from postdrop
which convert RFC822 files to internal files, and use these in your
program. We decided that this would be more hassle than it's worth.
