You may want to make sure UseCanonicalName is off, lest apache replace hostnames with the site's ServerName.

RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.domain1\.com$    [NC]
RewriteRule ^(.*)$       http://domain2.com$1   [R=301]

When redirecting from one domain name to another, you should also take the www prefix into account. This Rewrite rule will match the old domain name with or without the www prefix.

RewriteCond %{HTTP_HOST} ^(www\.)?olddomain\.com$    [NC]
RewriteRule ^(.*)$       http://newdomain.com/$1   [R=301]

or if you prefer to keep the www prefix, substitute this RewriteRule:

RewriteRule ^(.*)$       http://www.newdomain.com/$1   [R=301]
