Data type Distinguished Name of an MTA object
Multivalue (Array) No
Heuristic 4 => Replicated between sites, no operational attribute
Access category

Ex55 Database name Home-MTA

In principle, this is the specification of the home server whose distinguished name leads to the site name of course. The site is the one in which the mailbox is stored - and the MTA is representing the mail transport kernel of an Exchange 5.5 server.

The distinguished name of an MTA always starts with 'cn=Microsoft MTA', after that the DN of the regarding server follows. An example for an Home-MTA would be this:

cn=Microsoft MTA,cn=SRV1,cn=Servers,cn=Configuration,ou=Site1,o=CERROTORRE

Please note that server objects for Exchange 5.5 servers are always stored in the 'Configuration' container beneath the site. You should change the Home-MTA attribute only if you have moved the mailbox to another Exchange server. This is done with the Exchange 5.5 admin tool in the 'Advanced' tab of the mailbox object. However, mailboxes in Exchange 5.5 environments can only be moved intrasite and never between two different sites.
