Cool, thanks! Thanks to your input, I was able to track down a solution:
I searched Scrubber.py, and found some logic which said:
"if mm_cfg.SCRUBBER_USE_ATTACHMENT_FILENAME_EXTENSION"
so I edited mm_cfg.py and put in the following line:
SCRUBBER_USE_ATTACHMENT_FILENAME_EXTENSION = 1
then restarted mailman.sh
I'm extension-happy now.
