Hi,

HylaFAX supports passive connections (and i plan to support this too in
one of the next releases of WHFC).

A little bit documentation for the protocol can be found on a man-page
(if i remember correctly hfaxd ?). Also starting all the commands like
sendfax with for example "sendfax -v -v " gives a good overview how
the protocol works. Also reading the RFC for ftp (RFC 959) gives a lot
of useful informations.
