That's really more a procmail thing than a hylafax thing.

What you want to do is use procmail to capture the message if the subject is 
right; then you need a Perl, Python, PHP or Ruby script which will extract 
the PDF attachment into a file, then send it as a fax.  Easy enough.

First:  Get the appropriate library bindings for your favourite scripting 
language, to deal with multipart messages and sending faxes.
Second:  Write a script which will examine a multipart message on STDIN; and 
if a PDF attachment is detected, write it to a file under /tmp/.
Third:  Set up a test user, with a procmail recipe that calls up your script.
Fourth:  Check that e-mailing the test user with a PDF attachment actually 
calls your script and creates a temporary file.  When you are sure this is 
working, add a line to the script that fires off the sendfax command.
Fifth:  Test it some more.
Sixth:  Deploy it!
