Quoting the docs at meli.conf(5):
```text
custom_compose_hooks [{ name = String, command = String }]
(optional) Custom compose-hooks that run shell scripts.
compose-hooks run before submitting an e-mail.
They perform draft validation and/or transformations.
If a custom hook exits with an error status or prints output to
stdout and stderr, it will show up in the UI as a notification.
Example:
[composing]
editor_cmd = '~/.local/bin/vim +/^$'
embed = true
custom_compose_hooks = [ { name ="spellcheck", command="aspell --mode email --dont-suggest --ignore-case list" }]
```
