How to DISABLE automatically making a message as read in Mail

SquidlyMan figures out his own issue.
Ok…I take part of what I said back. It was MailActOn by InDev which allowed me to not automatically have a message marked as read. See http://indev.ca/MailActOn.html for more info.
Apparently the version I had loaded wasn’t compatible with Lion Mail.app. Since updating it, I know have this feature again.
