Про postfix ничего не могу сказать, а пэтч к popa3d чтобы он
регистрировался через whoson мне недавно прислали.

PROJECTS
Popa3d patch
Patch to use whoson (WHO iS ONline) protocol with Solar Designer's
tiny POP3 daemon - popa3d v0.4. You must have libwhoson library
instaled (see below). In this version of patch popa3d must be set as
standalone (required changes are included).
popa3d-0.4-whoson_0.1.patch
Usage:
tar zxpf popa3d-0.4.tar.gz
patch -p0 < popa3d-whoson.0.1.patch
edit params.h and Makefile for your own needs and compile it.
Note: Check out the followin settings in params.h used in standalone
mode:
MAX_SESSIONS 50
MAX_SESSIONS_PER_SOURCE 5
MAX_BACKLOG 5
MIN_DELAY
If you have clients behind firewall (for example with IP Masquerade)
you should change at least MAX_SESSION_PER_SOURCE.
