Hi Jon

Your postfix is having trouble resolving these domains - check what 
nameserver is being defined in /var/spool/postfix/etc/resolv.conf (which 
is normally generated from /etc/resolv.conf upon postfix loading) and make 
sure that nameserver is working correctly.  If necessary, change that to 
another (eg your ISP's nameserver)
