Sometimes, however, you need to send a slightly different message to each recipient (e.g. a password reset). The best way to do this is to place the whole message inside a <ui:repeat>:

<ui:repeat value="#{people}" var="p">
    <m:message>
        <m:from name="#{person.firstname} #{person.lastname}">#{person.address}</m:from>
        <m:to name="#{p.firstname}">#{p.address}</m:to>
            ...
    </m:message>
</ui:repeat>
