As others have pointed out, 400K addresses with full personalization  
is a big job that may well require some MTA tuning.  And a hosting  
service using cpanel is unlikely to be one that provides you with what  
you need. And it is also likely that some of the mailman tuning you  
need to do won't be available through cpanel.

The absolute first (well actually, second) thing you should do is talk  
to your hosting provider to see what they say about you sending to a  
list of 400K address with personalization.  Only after they say that  
they are okay with that, should you be asking about the mechanics of  
actually doing this.

And of course, the first thing that you need to do is make sure that  
you have evidence that each and every email address on that list is  
read by someone who how wants to be on that list.  That is, do you  
have a positive response to a confirmation request that was sent to  
each address?

Many of your earlier questions about proper SPF records and so on will  
depend on how your provider has set up mailman under cpanel.
