Best to remove IP version dependencies in your configs.

If you are using name-based virtual hosting in Apache, convert:

   Listen a.b.c.d:80         ->  Listen 80
   <Virtualhost a.b.c.d:80>  ->  <Virtualhost *:80>

Use hard-coded IP addresses only where required for stuff like SSL-enabled 
webhosts.

In postfix just add to main.cf:

   inet_interfaces = all
   inet_protocols = all

And make sure your MX hostnames have AAAA RRs.
