Ratelimit for email account per user

[retromega]

i know this might sound dumb but
for weeks i have searched the internet and i couldn’t find answers

in the admin panel

under MAIL → domain edit
Rate limit (Email / hour / account)

when i put something like : 20 / 1H / domain name

it return error invalid format

please can someone give me a hint or correct format to do this

Maybe we could provide an example of the file format in the backend or as a comment in the text field.
