mgetty+senxfax failures
I discovered today that the mgetty binary in my Red Hat 9.0 system wanted to reference /usr/lib/sendmail or not work at all. The problem presented itself as mgetty receiving a fax, spooling it to disk, and not doing anything else with it.
After creating a symlink for /usr/lib/sendmail (I’m using postfix instead of sendmail), mgetty was happy and resumed processing faxes like normal.
It’s an obscure problem, but potentially annoying.
