Specifies an object's aliases as known in a foreign messaging system.
A foreign e-mail alias is the return address value used when the NetWare MHS user sends e-mail to an X.400 user.
For example, a NetWare MHS user (a user whose mailbox is located on an MHS Messaging Server) can have an X.400 alias---with an X.400 native name---so that X.400 users can use this alias to send mail to the MHS user.
An object can have several foreign e-mail aliases, one for each type of foreign e-mail system.
