Just remove the terminating '/' at the end of the second condition tag....

<condition field="destination_number" expression="^(\d+)$">

Well, untested of course as I am busy with school:) But what I wrote up to try at
Christmas (with your addition) was:

<extension name="OutboundFax">
 <condition field="caller_id_number" expression="^204$"/>
 <condition field="destination_number" expression="^(\d+)$"/>
     <action application="answer"/>
     <action application="playback" data="silence_stream://2000"/>
     <action application="rxfax" data="/tmp/${uuid}.rxfax.tiff"/>

     <action application="system" data="/opt/freeswitch/scripts/emailfax.sh $1@fax.com /tmp/${uuid}.rxfax.tiff"/>

     <action application="hangup"/>
 </condition>
</extension>

Am I correct in presuming that Freeswitch will answer a fax from a local zap based user
just like it does from an FXO port connected to a POTS line? What I hope to do here is
catch any call made from that extension (the zap based fax machine/user) and push its
call into the fax module.

Yes, when a device (phone/fax/modem/whatever) is plugged into the FXS it gets dialtone and dials. Whatever it dials is put into ${destination_number} just like any SIP phone that dials. This extension looks ok. Try it out and let us know how it goes.
