flexfax: Is there an easier way to email faxes than modifying sendmail?

["David A. Bergstedt" <dbergstedt@umesc.er.usgs.gov>]

I was wondering if there would be an easier way than modifying sendmail
for allowing users to send faxes via email.

If the user would send email to say, sendfax@fax.foo (fax.foo the
hylafax server),
and fax.foo has a mail alias of

sendfax: "|/usr/local/fax/bin/faxmail -d ???"

where ??? could get the X-FAX-Dialstring info that is translated from
the message's subject header info, via a mapping in lib/faxmail.conf? I
don't know what you would put in the faxmail.conf (maybe
X-FAX-Dialstring: "Subject" ?) and I don't know how you would pass that
off on the command line to faxmail (the ??? above).

Is this possible or is this a stupid question?

Thanks in advance...

Dave
