Re: They knew who sent the e-mail - Were they sacked?
"There has to be a gateway setting that can prohibit or limit recipients on an email or just put those messages on hold until somebody higher up hits the "ok" button..."
Also, some gateway setting that delays emails sent (to all recipients or only those out of the organisation) by a couple of minutes, giving time to recall if it is caught in time. Won't be foolproof but at least can save some 'butterfingers' or 'temporary brainfart' moments
