Outlook Marking All Yahoo Group email as Spam

[TrishCat]

I recently upgraded from Outlook 2000 to Outlook 2007.

I belong to a yahoo email group and all the traffic from that group comes
through Outlook. In the subject header, it adds the word "spam" to the
subject heading, along with the name of the email group. Every time I reply
to a message I have to edit the subject line, and delete all that add'l
stuff. I always click "Mark as Not Spam", but still every message that comes
through has this issue. Any ideas?

outlook isn't doing it- a 3rd party antispam tool is. what firewall do you
use? what antivirus? It's one of those if you aren't using an anti-spam
scanner.

In addition to what Diane says, it could also be your ISP.
