This is the ninth in a series of messages describing new features in Isode R14.4, scheduled to ship in April 2009. You can see all of the messages on this blog relating to R14.4 by clicking on this link
MIXER is a standardized mapping between X.400 and Internet mail specified in RFC 2156. Addresses are mapped algorithmically, with MIXER mappings relating part or all of the domain of an Internet email address to O, OUs, ADMD, PRMD and Country of X.400 OR Addresses. This provides a convenient way to algorithmically map addresses, usually resulting in addresses that are reasonable for human users.
This mapping can be configured in the directory according to RFC 1838. M-Switch MIXER supports this, and provides GUI configuration of the MIXER mappings. A typical MIXER gateway will define a small number of these mappings.
R14.4 extends this core mapping to provide mappings for individual user addresses configured in the directory. A directory entry will hold both Internet and X.400 addresses for a user, and will map between these. This has the benefit of providing a completely flexible mapping for a community of users, and can also utilize information that is already configured in the directory where users have access to both Internet mail and to X.400.
There is flexible configuration for mapping in both directions. It is possible to use multiple directories, each handling different parts of the mail address space. The attributes used for the mappings are also configurable. This is important where a MIXER gateway supports multiple organizations, and there are existing directories for each organization holding the relevant information.
We believe that this will be a useful option for many organizations deploying MIXER gateways.
