htaccess rewrite problem

[RayYates]

I have the following redirects to get rid of some dead links showing up in search crawlers.

RewriteCond %{HTTP_HOST} ^www\.mydomain\.com$ [NC]
RewriteCond %{QUERY_STRING} ^unsubscribe&group=128f987fbc$ [NC]
RewriteRule ^scotmail/scotmail\.mvc$ http://www.mydomain.com [R=301,L]

What I expected is this
http://www.mydomain.com

Unfortunately the query string is getting sent to the address bar.
What I get is this

http://www.adomain.com/?unsubscribe&group=128f987fbc

What do I need to change?

I thought I had to use [QSA] to get the query string output.

You need a ? after the .com: .com? [R=301,L]

If you redirect to a root then the browser throws the original query string back on again, the ? tells it to strip it.

Thank you sir.
