Hello,

How can I block outgoing mail from the domain, except for a particular E-Mail address, or limit the sending from the domain per hour?
I want to use external servers (only), otherwise the Emails should be dropped - unless a particular Email was used. Like an Email whitelist.

Some users are abusing our outgoing mail :/

Thanks a lot,
Yossi
