Although installed as part of the base PMDF-MTA and PMDF-ACCESS
products, the PMDF MessageStore is licensed separately. Sites without a
license may create up to ten MessageStore user accounts in addition to
the default account. A PMDF-MSGSTORE license is required
to create more than ten user accounts for the MessageStore.
2.3 Accounts
MessageStore accounts have the same basic profile information as
popstore accounts. Indeed, the same underlying data structure is used
to describe both MessageStore accounts and popstore accounts. That
structure is shown in Table 1-1 . However, for MessageStore accounts
the message_count field of that structure is not used and
usually should have a value of zero.
Note that in the MessageStore, the account name post is
reserved. It is the mailbox name associated with the store's collection
of public folders. For instance, a message for post+staff@host is
delivered to the public folder named "staff".
2.3.1 Account naming
The MessageStore supports only one account naming scheme:
USERNAME_STYLE=3. When configuring the MessageStore, the PMDF
configuration utilities will automatically select that naming scheme.
See Section 1.3.1.1 for information on this naming scheme.
