We have this kind or setup. Incoming and outgoing mail is handled by the 
SMTP server in the DMZ. Destination domain is rewritten to allow the DMZ 
server to send the kolab e-mails to the proper kolab server, ie. 
incoming mail is rewritten from @ghs.fr (public domain name) to @int.ghs 
(private / internal domain name, corresponding to the kolab server), 
then sent to the proper machine.
The big drawback is that e-mail addresses and accounts in kolab are 
@int.ghs, the LDAP server publishes internal-only addresses that we must 
not use in external-going mails, etc.
I'm sure we could have done that a lot better, but now it's quite too 
late...
