.htacess existing URL from old domain, redirects to index.php on new domain - apache

Question

Problem
I have a new TYPO3 website on a new domain. All important pages of the old website point to their new counterpart for which I added individual 301 redirects in the .htaccess. Those work fine!
However there are pages which have the exact same URL as the old website, which I cannot add individual redirects for (infinite loop). For example /contact/. When I access http://www.example-old.com/contact/ the page simply redirects to /index.php. Why?
Wishlist
All non-www should be redirected to www (works)
Other domains should be redirected to new (works)
Referrals from the old website, should be redirected to the same URL on the new domain, unless a manual 301 redirect is in place. (does not work)
Current setup
This is the .htacess snippet I'm working with:
<IfModule mod_rewrite.c>
# Enable URL rewriting
RewriteEngine On
RewriteBase /
# Point old domain to new domain
RewriteCond %{HTTP_HOST} ^example-old\.com$ [NC,OR]
RewriteCond %{HTTP_HOST} ^example-new\.com$ [NC]
RewriteRule ^(.*) http://www.example-new.com/$1 [R=301,L]
# Point idle domains to new domain
RewriteCond %{HTTP_HOST} ^/?(?:www\.)?example-01.nl [OR]
RewriteCond %{HTTP_HOST} ^/?(?:www\.)?example-02.de [OR]
RewriteCond %{HTTP_HOST} ^/?(?:www\.)?example-03.eu [OR]
RewriteCond %{HTTP_HOST} ^/?(?:www\.)?example-04.net [OR]
RewriteCond %{HTTP_HOST} ^/?(?:www\.)?example-05.org
RewriteRule ^(.*)$ http://www.example-new.com/$1 [R=301,L]
</IfModule>
I have tried every combination I could find to try and get this to work. What could be going wrong here?
Many Thanx!

Try to remove the leading "/?" and the inner "?:" also escape the last dot from your http host conditions:
RewriteCond %{HTTP_HOST} ^(www\.)?example-01\.nl$ [OR]
RewriteCond %{HTTP_HOST} ^(www\.)?example-02\.de$ [OR]
RewriteCond %{HTTP_HOST} ^(www\.)?example-03\.eu$ [OR]
RewriteCond %{HTTP_HOST} ^(www\.)?example-04\.net$ [OR]
RewriteCond %{HTTP_HOST} ^(www\.)?example-05\.org$
RewriteRule ^(.*)$ http://www.example-new.com/$1 [R=301,L]

If you remove the ^ from the first RewriteCond all request to the old domain will be redirected to the new domain.
If you want the specific redirects to have priority make sure you put them before this one.
# Point old domain to new domain
RewriteCond %{HTTP_HOST} example-old\.com$ [NC,OR]
RewriteCond %{HTTP_HOST} ^example-new\.com$ [NC]
RewriteRule ^(.*) http://www.example-new.com/$1 [R=301,L]
