Can't POST

I've just set up sn for some local newsgroups. As soon as I can connect to
the server, there is an error message:

snntpd:open(fifo):No such file or directory(ok)

Nevertheless I am able to list the (empty) local newsgroups I just created.
But when I try to POST:

Usage: POST [-options] <url>...
    -m <method>   use method for the request (default is 'POST')
    -f            make request even if POST believes method is illegal
    -b <base>     Use the specified URL as base
    -t <timeout>  Set timeout value
    -i <time>     Set the If-Modified-Since header on the request
    -c <conttype> use this content-type for POST, PUT, CHECKIN
    -a            Use text mode for content I/O
    -p <proxyurl> use this as a proxy
    -P            don't load proxy settings from environment
    -H <header>   send this HTTP header (you can specify several)

    -u            Display method and URL before any response
    -U            Display request headers (implies -u)
    -s            Display response status code
    -S            Display response status chain
    -e            Display response headers
    -d            Do not display content
    -o <format>   Process HTML content in various ways

    -v            Show program version
    -h            Print this message

    -x            Extra debugging output
snntpd:do_post:POST died with 255

Any ideas what I did wrong / forgot?

The command line:

env - PATH=/home/jain/news/sn/bin:$PATH ./ucspi-tcp/tcpserver -RHl0v -x
news.cdb 0 1119 snntpd
