.SH NAME
vmm.cfg \- configuration file for vmm
.\" -----------------------------------------------------------------------
.SH SYNOPSIS
vmm.cfg
.\" -----------------------------------------------------------------------
.SH DESCRIPTION
.BR vmm (1)
reads its configuration data from
.IR vmm.cfg .
.PP
The configuration file is split into multiple sections.
A section starts with the section name, enclosed in square brackets
.RB ` [ "' and `" ] ',
followed by
.RI ` option " = " value '
pairs.
.br
Whitespace around the `=' and at the end of a value is ignored.
Empty lines and lines starting with `#' or `;' will be ignored.
.PP
Each value uses one of the following data types:
.TP 8
.I Boolean
to indicate if something is enabled/activated (true) or
disabled/deactivated (false).
.br
Accepted values for
.I true
are:
.BR 1 , " yes" , " true" " and " on .
.br
Accepted values for
.I false
are:
.BR 0 , " no" , " false" " and " off .
.TP
.I Int
an integer number, written without a fractional or decimal component.
.br
For example
.BR 1 , " 50" " or " 321
are integers.
.TP
.I String
a sequence of characters and/or numbers.
.br
For example
.RB ` word "', `" "hello world" "' or `" /usr/bin/strings '
are strings.
.PP
Most options have a default value, shown in parentheses after the option's
name.
In order to use a option's default setting, comment out the line, either
with a
.BR # " or " ;
or simply remove the setting from
.IR vmm.cfg .
.PP
A minimal
.I vmm.cfg
would be:
.PP
.nf
[database]
user = me
pass = xxxxxxxx

[misc]
dovecot_version = 1.2.16
.fi
.\" -----------------------------------------------------------------------
.SH SEARCH ORDER
By default
.BR vmm (1)
looks for the
.I vmm.cfg
file in the following directories in the order listed:
.RS
.PD 0
.TP
.I
/root
.TP
.I
/usr/local/etc
.TP
.I
/etc
.PD
.RE
.PP
The first configuration file found will be used.
.\" -----------------------------------------------------------------------

.I Boolean
.PP
Determines the behavior of
.BR vmm (1)
when an account is deleted (userdelete).
If this option is set to

.PP
This could be slow on large Maildirs.
When you have enabled quotas,
.BR vmm 's
userinfo subcommand will also display the current quota usage of the
account.
You may also use userinfo's optional details\-argument
.BR du " or " full ,
in order to display the current disk usage of an account's mail directory.
.\" ------------------------------------
.SS account.password_length
.BR password_length " (default: 8) :"

`SKEY'.
This binary will be also required if your Python installation doesn't
support the:
.IP \(bu 4
md4 hash algorithm (hashlib + OpenSSL or PyCrypto) used for the password
schemes: `PLAIN\-MD4' and `NTLM'
