mcom(1)'s do_mime calls file -Lbi to get a mime-type for a file to be attached. On macOS, the -i option to the vendor's /usr/bin/file means something else, the flag to print a mime-type instead of the human-readable string from the magic file is -I (uppercase i). I'd propose a patch but I have no ideas offhand about how to handle this.
