Limit outgoing email

[goppegard]

When providing demo zimbra accounts, I want to limit the number of outgoing emails to 200/day in the event someone tries to use it for spam purposes.

I haven't been able to find an account, domain, or COS attribute to limit the number of emails sent by an account. Any ideas on how to implement this?

Welcome to the forums

Sender Throttling or you could look at using the inbuilt policy features of Postfix and roll your own code that will track the number of emails sent.

Hope that is of some help to you.
