postfix::config { 'transport_maps'
  ensure  => present,
  value   => 'hash:/etc/postfix/transport',

#### Examples

### postfix::virtual

Manages the contents of the virtual map.

#### Requirements
Augeas is, of course, required.

The following code is necessary to make virtual maps work:
```puppet
include postfix

postfix::hash { '/etc/postfix/virtual':
  ensure => present,
}

postfix::config { 'virtual_alias_maps':
  ensure  => present,
  value   => 'hash:/etc/postfix/virtual',
}
```
#### Parameters
##### `ensure`
A string whose valid values are present or absent.  
Default: present.

##### Route mail bound for 'user@example.com' to root.
```puppet
postfix::virtual {'user@example.com':
    ensure      => present,
    destination => 'root',
}
```

### postfix::conffile

Manages postfix configuration files. With it, you could create configuration files (other than, main.cf, master.cf, etc.) restarting postfix when necessary.

#### Parameters
##### `ensure`
A string whose valid values are present, absent or directory.  
Default: present.  
Example: absent.

Default: `undef`  
Example: 'puppet:///modules/postfix/configfile.cf'  

##### `content`
The content of the postfix configuration file. This is an alternative to the `source` parameter. If you don't provide `source` neither `content` parameters a default template is used and the content is created with values in the `options` hash.  
Default: `undef`  

##### `path`
Path where to create the configuration file.  
Default: '/etc/postfix/${name}'

##### `mode`
Permissions of the configuration file. This option is useful if you want to create the file with specific permissions (for example, because you have passwords in it).  
Default: '0644'  
Example: '0640'

##### `options`
Hash with the options used in the default template that is used when neither `source` neither `content`parameters are provided.  
Default: {}  
Example:
```
 postfix::conffile { 'ldapoptions.cf':
   options            => {
     server_host      => ldap.mydomain.com,
     bind             => 'yes',
     bind_dn          => 'cn=admin,dc=mydomain,dc=com',
     bind_pw          => 'password',
     search_base      => 'dc=example, dc=com',
     query_filter     => 'mail=%s',
