Hi @Anachron, thank you for sharing your approach for opening html emails. I built upon your example for an approach that works for me:

```
ATTACH="$(mshow -t . | dmenu)"
MIME="$(echo "$ATTACH" | cut -f 2 -d ":" | cut -f 2 -d " ")"
ATTACHNUM="$(echo "$ATTACH" | cut -f1 -d':')"

tmp="$(mktemp '/tmp/mblaze.XXXXXX')"
mshow -O . "$ATTACHNUM" > "$tmp"
# replace this with xdg?
case "$MIME" in
	"application/pdf")
		zathura "$tmp"
		;;
	"text/html")
		firefox "$tmp" 
		;;
# More stuff for pngs and stuff?
esac
```

I use it as a general tool for extracting all attachments in emails in my email script I made for my pinephone:

I dont know if my approach is the best but it works for emails with multi html and works as a general attachment extractor.
