Avoiding having a www A REC with BIND9

Hi Longman,
I'm not 100% sure I see your problem, as I think I'm doing what you  
want to do already with my domain name and it's just fine:
; <<>> DiG 9.3.4-P1 <<>> www.minimal.cx A
;; global options: printcmd

SMTP RDNS is much more strict than HTTP, so I have my IP map back to  
my name server with an A record, then have a CNAME for my www on the  
same public IP.

Is this what you mean ?  If so I can post fragments of my BIND config,  
but if not, could you describe what you're not allowed to do ?

HTH,
