Hybrid Email Interoperability

Not all businesses are the same and in world of convergence, interoperability is necessary in some organizations to share an email domain between two distinct email systems.

What is Email Interoperability

Environment of email systems co-exist and interoperate for migrating mailboxes over a period of time for the same email domain, where mail needs to be delivered to two or more different messaging systems. We are often asked how to configure the Zimbra Collaboration Server so that some accounts are moved/migrated to Zimbra but other accounts continue to live on the existing mail system.

Zimbra Enterprise Email

Hybrid email interoperability or co-existence is possible if the other mail system offers some of the mail routing features that Zimbra offers. Zimbra Split Domain configuration which email delivery provides for email users in a single domain to reside on different email providers and allows for incremental migrations from a legacy provider to a new platform. During the migration process, one system is designated as the “primary” mail store and is responsible for receiving and routing mail for the domain (mydomain.com). The other system is considered the “secondary” mail store.
