If a user does not have an INBOX already, and the INBOX is to be created,
create the list of folders in this setting as well.
*autocreate_inbox_folders* is a list of INBOX's subfolders separated by a
"|", that are automatically created by the server under the following two
scenarios. Leading and trailing whitespace is stripped, so "Junk | Trash"
results in two folders: "Junk" and "Trash".  See also the *xlist-flag*
option, for setting special-use flags on autocreated folders.

INBOX folders are created under both the following conditions:

1.
    The user logins via the IMAP or the POP3 protocol.  *autocreate_quota*
    option must have a value of zero or greater.

2.
    A message arrives for the user through the *lmtpd(8)*.
    *autocreate_post* option must be enabled.
