Q&A: Is there a way to use a UCR attribute to limit the number of emails a user can send?

Question:

Is there a way to use a UCR attribute to limit the number of emails a user can send (e.g. per hour or per day)?

Answer:

No, we currently don’t have such a variable, but you can use your local postfix config (/etc/postfix/main.cf.local) to make changes, which can’t be done via ucr.
