That doesn't really tell us much, what exactly are you trying to do and why? What would using ZImbra in this scenario give you?

I want to use Zimbra only gateway e-mail.

You would be better to install Postfix, SpamAssassin and Clam AV instead; especially as you do not want to use the collaboration functionality of Zimbra.

If you don't want to use the collaboration features of Zimbra, you would be better off to just configure intelligent message filtering and RBLs on your existing Exchange server.

If your Exchange server is overloaded with too much Junk email and doesn't have the resources to do additional filtering, then either get another Exchange Server and configure it as a front-end server or get a firewall like a SonicWall with the comprehensive gateway security suite, which does anti-virus, anti-malware and RBL checking.

If you try to configure a separate Postfix server to do this, you'll need to script and schedule periodic dumps of valid SMTP addresses from AD to avoid backscatter between your Exchange server and the Postfix server.

For the $1,400 or so for another Windows Server and Exchange Server pair of licenses (and about the same or less for a SonicWall sized correctly for your installation), you'll save your self hours and and hours of hassle--and complaints from users when their mail goes missing until you get the scripts exactly right.

Now, if you are not happy with your Exchange installation or if you want to deploy a better groupware solution that uses a lot less resources than Exchange, then you should consider doing a migration from Exchange to Zimbra.

But deploying Zimbra just to do front-end MTA work for Exchange is IMHO not the easiest nor the most cost-effective solution.

Hope that helps,
Mark

Or perform LDAP looks like I do from Postfix front-end MTA back to Zimbra.

That works too; you just want to be careful that you use a Windows account to do the Active Directory LDAP query which has no write authority to Active Directory, else if the front-end MTA gets hacked AD will not be far behind.

Hope that helps,
