The "best" that can be done right now is to use this in 
/var/spool/hylafax/etc/FaxModify:

FIXEDWIDTH=-dPDFFitPage

... this should cause any landscape pages to be shrunk to fit 
horizontally onto a portrait page.

Understand that HylaFAX uses Ghostscript for all of its document 
processing, and thus for the auto-rotate feature to be properly 
placed... it should be in Ghostscript.  You may want to bring this issue 
up with the Ghostscript development team.

Ghostscript doesn't give us any nice tools to do that in an automated 
fashion.  There is a distiller AutoRotatePages feature, but I can't 
figure out if that is supposed to work in our usage and if it does what 
the right way to use it is.

If you know of some way to reliably get Ghostscript to auto-rotate 
landscape pages to portrait for both Postscript and PDF... then let us 
know.  I looked into it two years ago and didn't find anything reliable.

Make sure that you consider the worse-case scenario where the user 
submits multiple files with multipage documents where some pages are 
rotated portrait while others are rotated landscape.

It's very difficult to "fix" this properly on HylaFAX's end.  My opinion 
is that this is something that Ghostscript should be able to do.

Thanks,

Lee.
