Hi all:

Currently we have a Sendmail-based mail system, in two separate servers:

1) LAN Server, with user mailhubs
2) DMZ Server, which acts as a relay MTA.

We're planning to deploy a Zimbra-based infraestructure with the following servers:

1) LAN Zimbra server: Zimbra mail Server + Zimbra LDAP
2) DMZ Zimbra MTA: relay in the DMZ zone.

Is it possible to access ZImbra server through Zimbra MTA in the DMZ zone via Internet? We need to provide web access to users through Internet, but we cannot open any port directly to the LAN zone, so access via DMZ server would be desirable .

Is Zimbra HTTP proxy a solution? If we deploy it in the DMZ Server, is it possible to configure it so that users can access Zimbra Server in the LAN zone through it?

Thanks in advance!
