&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;* &amp;#039;&amp;#039;&amp;#039;parameter&amp;#039;&amp;#039;&amp;#039;: virtual_mailbox_maps&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;default&amp;#039;&amp;#039;&amp;#039;: empty&lt;br /&gt;
==About==&lt;br /&gt;
Optional lookup tables with all valid addresses in the domains that match $[[../virtual_mailbox_domains|virtual_mailbox_domains]].&lt;br /&gt;
&lt;br /&gt;
In a lookup table, specify a left-hand side of &amp;quot;@domain.tld&amp;quot; to match any user in the specified domain that does not have a specific &amp;quot;user@domain.tld&amp;quot; entry.&lt;br /&gt;
&lt;br /&gt;
The [http://www.postfix.org/virtual.8.html virtual(8)] delivery agent uses this table to look up the&lt;br /&gt;
per-recipient mailbox or maildir pathname.  If the lookup result ends in a slash (&amp;quot;/&amp;quot;), maildir-style delivery is carried out, otherwise the path is assumed to specify a UNIX-style mailbox file. Note that $[[../virtual_mailbox_base|virtual_mailbox_base]] is unconditionally prepended to this path.&lt;br /&gt;
&lt;br /&gt;
When a recipient address has an optional address extension (user+foo@domain.tld), the [[http://www.postfix.org/virtual.8.html virtual(8)] delivery agent looks up the full address first, and when the lookup fails, it looks up the unextended address (user@domain.tld).&lt;br /&gt;
&lt;br /&gt;
Note 1: for security reasons, the [http://www.postfix.org/virtual.8.html virtual(8)] delivery agent disallows regular expression substitution of $1 etc. in regular expression lookup tables, because that would open a security hole.&lt;br /&gt;
&lt;br /&gt;
Note 2: for security reasons, the [http://www.postfix.org/virtual.8.html virtual(8)] delivery agent will&lt;br /&gt;
silently ignore requests to use the [http://www.postfix.org/proxymap.8.html proxymap(8)] server. Instead&lt;br /&gt;
it will open the table directly. Before Postfix version 2.2, the [http://www.postfix.org/virtual.8.html virtual(8)] delivery agent will terminate with a fatal error.&lt;/div&gt;</summary>
