httpd with PATH_INFO required
Not all web servers support/supply the PATH_INFO variable that's needed by Nullwebmail. But the code is easy to hack and it took me less than an hour to make my, er, rudimentary httpd happy.
Nice piece of software. Nice example for well-written code.
Dang! It took me quite a while to figure out why I could not post to local newsgroups - the entry in hosts.allow was not working as advertised in the documentation.
For those with similar problems, modify the snntpd line in inetd.conf:
nntp stream tcp wait root /usr/sbin/tcpd /usr/bin/env POSTING_OK='' /usr/local/sbin/snntpd logger -p news.info
Would be cool if it were mentioned in the documentation.
Apart from that, cool product. If only it had authentication...
