+=head1 NAME
+
+Sietima::Role::WithPostAddress - role for lists with a posting address
+
+=head1 SYNOPSIS
+
+  my $sietima = Sietima->with_traits('WithPostAddress')->new({
+    %args,
+    return_path => 'list-bounce@example.com',
+    post_address => 'list@example.com',
+  });
+
+=head1 DESCRIPTION
+
+This role adds an L<< /C<post_address> >> attribute, and exposes it
+via the L<< C<list_addresses>|Sietima/list_addresses >> method.
+
+On its own, this role is not very useful, but other roles (like L<<
+C<ReplyTo>|Sietima::Role::ReplyTo >>) can have uses for a post
+address.
+
+=head1 ATTRIBUTES
+
+=head2 C<post_address>
+
+An L<< C<Email::Address> >> object, defaults to the value of the L<<
+C<return_path>|Sietima/return_path >> attribute. This is the address
+that the mailing list receives messages at.
