Beginning with V8.7, the RHS of a rule used to select an error or discard delivery agent can look like this: R... $#error $@ dsn $: text of error message here R... $#discard $: discard For the error delivery agent, the text following the $ : is the actual error message text that will be included in bounced mail or sent back to a connecting SMTP host. For the discard delivery agent, the text following the $ : is generally the literal word discard . [13]
