I've had the same experience with Firefox.  Some files appear to contain
an instruction to the printer that subverts duplexing, and the CUPS
driver isn't able to see that signal and replace it with the settings
for the printer.  Acroread apparently is able to send the file to the
printer without embedded instructions that subvert the CUPS driver's
settings.

I think Milan said evolution doesn't insert such an instruction.  So it
was probably within the message, which was html.  It would be nice if
evolution could find it and remove it.
