The <span><strong class="command">accept</strong></span> router has no private options of its own. Unless it is being
used purely for verification (see <span><strong class="option">verify_only</strong></span>) a transport is required to
be defined by the generic <span><strong class="option">transport</strong></span> option. If the preconditions that are
specified by generic options are met, the router accepts the address and queues
it for the given transport. The most common use of this router is for setting
up deliveries to local mailboxes. For example:
</p>
<pre class="literallayout">localusers:
driver = accept
domains = mydomain.example
check_local_user
transport = local_delivery
</pre><p>
The <span><strong class="option">domains</strong></span> condition in this example checks the domain of the address, and
<span><strong class="option">check_local_user</strong></span> checks that the local part is the login of a local user.
When both preconditions are met, the <span><strong class="command">accept</strong></span> router runs, and queues the
address for the <span><strong class="command">local_delivery</strong></span> transport.
