Would Automator be able to snag the file as it's coming in? The thing is: we need it to change format before the OS X fax service emails the fax, and I don't see how Automator can interrupt the process. It's worth a try, though.
Ideally, I'd like to change the default file format for the built-in fax service to JPG, so that it's JPG at initial save.
The main reason the file format needs to be JPG is due to my organization's use of Thunderbird in a heterogeneous environment (Windows and Mac). If we all used Macs (and in an ideal world, we would), Apple Mail could do the job without any problems.
And Mithras: 2 years, 6 months is a bit of a lurk, yeah.
