* configuration syntax
Statements that allow for variable substitution also allow for command
expansion. Commands are invoked the same way as in shell:
$(command [args...])
The following commands are defined:
- localpart X
Treats X as an email address and returns its part preceding
the @-sign. If there is no @-sign, returns X unchanged.
- domainpart X
Treats X as an email address and returns the part following
the @-sign. If there is no @-sign, returns empty string.
- shell CMD [ARGS...]
Runs the shell command CMD with the given arguments. Returns
the standard output from the command. The command is invoked
using "/bin/sh -c" and can contain any valid shell construct.

Namespace configuration completely rewritten. The "namespace" block
statement defines a particular namespaces. Within it, one or more
"prefix" statements define prefixes available in that namespace, along
with their mappings to the server filesystem, hierarchy delimiters etc.
An example of namespace configuration:
namespace personal {
prefix "" {
directory "$home/mailfolder";
}
prefix "#MH:" {
directory "$home/Mail";
delimiter "/";
mailbox-type "mh";
}
}

@cindex IMAP4 namespace
GNU @command{imap4d} supports a notion of @dfn{namespaces} defined

has certain permissions. It should be understood that these permissions
apply only if the underlying filesystem allows them.
in RFC 2342. A namespace can be regarded as a list of triplets,
defining locations to which the user has certain access rights. Each
triplet defines the @dfn{prefix}, under which the mailboxes can be
found, @dfn{hierarchy delimiter}, a character used to delimit parts of
a path to a mailbox, and a @dfn{directory} on the file system on the
server, which actually holds the mailboxes. Among these three values,
only first two are visible to the client using the IMAP
@samp{NAMESPACE} command.
The three namespaces supported by @command{imap4d} are:
There are three namespaces:

To change these defaults, use @code{shared-namespace} and
@code{other-namespace} configuration statements:
@table @command
@item shared-namespace @var{list}
Set shared namespace.
@item other-namespace @var{list}
Set other users' namespace.
@end table
For both statements, the argument is a list of directories that belong
to this namespace, e.g.:
These defaults can be changed using the @code{namespace} block

@example
shared-namespace (/var/spool/mail,/var/mail);

directory @var{path};
delimiter @var{chr};
mailbox-type @var{type};

@end example
If during the session the user creates a mailbox within either of
these namespaces, the mode of the mailbox is determined by the
following configuration statements:
@table @command
@item shared-mailbox-mode @var{mode}
Set file mode for mailboxes created in shared namespace.
@item other-mailbox-mode @var{mode}
Set file mode for mailboxes created in other users' namespace.
@end table
The @var{name} argument to the @code{namespace} statement declares
which namespace is being configured. Allowed values are:

The @code{prefix} statement configures available prefixes and
determines their mappings to the server's file system. The @var{pfx}
argument defines the prefix which will be visible to the IMAP client.
The @code{directory} statement defines the directory in the file
system to which @var{pfx} is mapped. Its argument can contain
references to the following variables(@pxref{Variables}):
@table @asis
@item user
Login name of the user.
@item home
Home directory of the user.
@end table
Exactly one @code{directory} statement must be present in each
@code{prefix} block.
The @code{delimiter} statement defines the folder hierarchy delimiter
for that prefix. It is optional, the default value being @samp{"/"}.
The @code{mailbox-type} statement declares the type of the mailboxes
within that prefix. If present, its argument must be a valid mailbox
type (e.g. @samp{mailbox}, @samp{maildir}, or @samp{mh}). The IMAP
@code{LIST} command will display only mailboxes of that type. The
@code{CREATE} command will create mailboxes of that type.
In the absence of the @code{mailbox-type} statement, the IMAP
@code{LIST} command will display mailboxes of any type supported by
Mailutils. The type of newly-created mailboxes is then determined by
the @code{mailbox-type} statement (@pxref{mailbox-type}).
Any number of @code{prefix} blocks can be present.
Consider, for example, the following configuration:
@example
@group
namespace personal @{
prefix "" @{
directory "$home/mailfolder";
@}
prefix "#MH:" @{
directory "$home/Mail";
delimiter "/";
mailbox-type "mh";
@}
@}
@end group
@end example
It defines the personal namespace containing two prefixes. The empty
prefix is mapped to the directory @file{mailfolder} in the home
directory of the currently authenticated user. Any type of mailboxes
is supported within that prefix.
The prefix @samp{#MH:} is mapped to the directory @file{Mail} in the
home directory of the user, and is limited to contain only mailboxes
in MH format.
Note that if the prefixes @samp{""} is not defined in the personal
namespace, the following default will be automatically created:
