Would you mind to show your filterfile and relevant parts of your config
file? Does your config file mention the filterfile? Maybe there's a
small typo some other pair of eyeballs can easily find.

Does your upstream server know the "XOVER" command? (The log should
reveal if leafnode falls back to XHDR otherwise.)

1. leafnode uses perl-compatible regular expressions
2. multiline matching is not provided for
3. the body is not matched against when filtering, just the header

It had never been designed for such things. Leafnode 2 developer
versions (which are not ready for production yet) try to do some
pipelining to get news

Indeed, fetchnews only returns a value other than 0 if it fails to start
up (like: configuration file missing), but once it has tried to contact
a server, the return value is always zero. Sorry for that, I'll see if I
can fix things for 1.9.23.
