FIFO pipes have names in the filing system, right? So to make Exim write
to one, you just get it to deliver to the path as if it were a file. Use
the appendfile transport, or use "save" in a filter, or use a file name
in an alias or conventional forward file (which also end up in an
appendfile transport).
I've never done this, and I'm not sure how the locking would work. You
may well have to disable locking by lock file, but I assume the fcntl
lock would work. If not, you have a problem with interlocking two
simultaneous deliveries - which is also a problem if you deliver to a
script which just writes to the FIFO without locking.
