Interestingly - how they did it with sendmail and qmail? There should
be some configs for them in chroot at least, so that really looks like
separate "instance" of them in there...

You can use mini_sendmail program for that (it is mentioned several
times on this list recently) -- it is tiny sendmail-semi-compatible
program that accepts mail on command line/stdin and passes it to
localhost:smtp.

Alternatively, you can use postfix's sendmail on linux-2.4 with glued
together /var/spool/postfix/postdrop directories -- see thread subjected
"Multiple maildrops ?" last week.

Source code is documented -- there is a man page for each routine and
what's it does inside each source file, and a shell script to extract
that page in mantools/ subdir. BTW, for your question -- you have
no good choice to talk to main postfix instance from your chroot jail
even if you know protocols... It's far better/simpler to use standard
protocols for that.
