I was looking at the configuration documentation for configuring altermime and the domain disclaimer admin UI. The installation looks fairly straight forward provided that you are using CentOS or RHEL5 32-bit usig the RPM and deploying the domain_disclaimer_Extension_Admin_UI zimlet. Unfortunately, our Zimbra server is running on RHEL5 64. The instructions for manually building and configuring altermime seem somewhat involved and I'm wondering if the manual installation process would have to be repeated after each Zimbra installation or upgrade?

Are there any other methods for implementing a domain level disclaimer at the footer of all outgoing emails with Zimbra on a 64-bit RHEL5 system?
