NewsMate   
by KnoWare Technology   

Brother to NewsMate Lite,
this program uses a full-featured database. With the use of the database,
multi-part files are automatically recombined. You can also specify a list
of authors to ignore, keep cross-posted articles from being re-downloaded
and also filter out duplicate filenames. Like the NewsMate Lite it supports
multiple news servers and has many filtering options to reduce spam posts.
It is very easy to use.
