Re: What is compromized in this situation?

We get them too but the ones where they spoof our domains are 100% caught with a few SA (SpamAssassin) custom rules and are scored to junk or discard since they can not sign (DKIM) their messages with our keys nor originate from our servers (SPF).

Re: Is there a way to create a trigger/alert that will notify me when something specific happens in Zimbra?
