First, many continue to change the information in their posting name,
thereby bypassing the block sender list. Second, IE does not allow for
blocking of cross posters.

So, here's what you can do:

Go to Tools, Message Rules, and create a rule that covers
things/subjects/senders you want to block.

Example: I have a rule that is;
Apply this rule after the message arrives

Where the Subject line contains 'the greatest news'

Delete it

It will then delete from my view any post that has the words "the greatest
news" in the subject line. You can do similar with some posters using their
name or variations.

When all else fails, highlight the subject line, press the delete key, and
confirm that you want that thread permanently deleted.

Others swear by Agent. I tried it and didn't like it. I did get IE Quote Fix
and that has made bottom posting easier.

1. Forget Outlook Express: it simply doesn't have the level of filtration
that you want.

2. Go to <http://www.download.com/Xnews/3000-2164_4-10144167.html> and
download XNews - it *does* have what you want.

XNews is *FREE* and, IMNSHO, is as good as they get.

Might try this.  It's no longer in production but will filter cross post.

Using Outlook Express.  Go to www.mozilla.org and download either
Mozilla (browser + mail client and newsreader) *or* Firefox (browser)
and Thunderbird (mail client and newsreader).  They cost nothing, they
work, you'll never go back to untabbed browsing, and if you really don't
like them you'll have wasted a bit of time but no money.  Oh, and they
are less frequently attacked by viruses, too.
