How to add zimbraMailTransport for not-relayhost'ed domain?

[DRVTiny]

Hello!
I've configured Zimbra for domain.com on the NAT'ed internal server as described in:
Split Domain - Zimbra :: Wiki
So... now absolutely all mail for non-local recipients goes to external relayhost. And it's pretty good with one important exception: I have an internal domain, which must be accessed directly (not within the relayhost).

How to add such "direct" transport for internal domain (with MX and A-records properly configured) named lists.domain.com and hosted on lists.domain.com server?

P.S. I need something like lists.domain.com=smtp:[lists.domain.com]:25 or lists.domain.com=smtp:lists.domain.com, but where and how to add it? And this transport must have highest priority.

Quite right, is the any other DNS server software to match it?

Yeah! All works for me!

My domain object in LDAP looks like this

dn: dc=lists,dc=domain,dc.com
objectClass: dNSDomain2
objectClass: domainRelatedObject
objectClass: zimbraMailRecipient
associatedDomain: lists.domain.com
sOARecord: ldap.domain.com. noc.domain.com. 2011010600 3600 900 36000 3600
nSRecord: ldap.domain.com
dc: lists
mXRecord: 10 lists.domain.com
aRecord: 192.168.152.101
zimbraMailTransport: smtp:[lists.domain.com]:25
zimbraMailStatus: enabled
zimbraMailDeliveryAddress: lists.domain.com

So this is DNS domain (PowerDNS probably the best DNS server in the world! ), but with transport records for Zimbra's Postfix.
