Problem with reverse names using double zones

Hi,

I have a domain like "AAA.BBB" registered at IANA. On the server side, I 
have two zones that I will call "AAA.BBB" and "ZZZ.AAA.BBB" (I have two 
.db files in my named.conf file). The first zone is where I put all the 
IPs used by my users plus my servers. The second zone is where I put the 
MX record, so my mail server uses "ZZZ.AAA.BBB" as domain.

The problem I´m facing is that the reverse file is directing the 
"AAA.BBB" zone, but not the "ZZZ.AAA.BBB", and some mail servers are not 
accepting messages from my domain because they are not identifying the 
reverse table for "ZZZ.AAA.BBB". If I set the "ZZZ.AAA.BBB" zone with 
reverse, I lose the other zone.

Here is a summary to clarify:

ZZZ.AAA.BBB.db (directing some servers + the mail server)
AAA.BBB.db (directing some servers + desktops)
AAA.BBB.rev (directing the reverse of AAA.BBB zone)
ZZZ.AAA.BBB.rev (directing the reverse for ZZZ.AAA.BBB zone)

named.conf is referencing the three files but not the last reverse, 
because the zone name is unique for the reverse (0.0.0.in-addr.arpa).

Do you know how can I solve this problem? Some of you has a light for 
this problem?

Thanks for any information.

Regards.
