Comment:
I'm thinking of a slightly more general feature, something like

```
replyfrom() {
        addrs="$(maddr -a -h reply-from "$MBLAZE/profile")"
        grep -Fv -e "addrs"
}
addr=$(maddr -a -h to:cc:bcc: "$1" | replyfrom | head -n 1)
if [ -n "$addr" ]; then
	from=$(maddr -h reply-from "$MBLAZE/profile" | grep -xi -e "<$addr>" | head - n1)
fi
if [ -z "$from" ]; then
	from=$(mhdr -h local-mailbox "$MBLAZE/profile")
fi
```
