Comcast uses Giganews and they don't provide all the headers. So if you
have any XOVER filters then you have a problem. Delete those filters.
Filters like on path, organization, newsgroups headers.

More precisely:

Giganews doesn't *index* most headers in their overview.fmt database.
When a news reader evaluates a filter, it sends the XHDR command to the
server to obtain filtered lists of messages based on the filter
criteria. The XHDR command is limited to the same set of headers as the
XOVER command - namely only those headers contained in the overview.fmt
database. So when you create a filter in that looks at a header that is
not in the server's overview.fmt database, the server bitches that that
header is not supported.

Giganews confirmed to me that their overview.fmt database contains only
these headers:

Subject
From
Date
Message-ID
References
Bytes
Lines

If you try to create a filter in MT-NW for any other header, the news
reader bitches about it and won't open news groups anymore.

I've edited my filters list for comp.sys.mac.system to only have the
filters that rely on Subject or From. I still get the complaint. Can
you think of somewhere else besides the filter list that would have my
previous filters on things like NNTP Host?

You're in luck, though. Supernews *does* index most news headers in
their database. And Supernews happens to be a bit cheaper than Giganews,
to boot:

Well, for me, Giganew is as cheap as it gets: free. That is, it is
"free" with my comcast subscription.

Many here have switched from Giganews to Supernews (myself included) and
have high praises of Supernews in comparison.

Not only does Supernews index all headers (or at least most of them), it
also does much better server-side SPAM filtering. That means a large
majority of the SPAM that others see in these news groups simply never
shows up to Supernews users. The amount of SPAM I see after switching
from Giganews to Supernews dropped dramatically! That, in itself, is
reason enough to switch if you ask me!
