> In my specific case, Exim mailhubs for an internal Exchange server that
accepts all messages at RCPT. After it accepts delivery, it realizes the
address is undeliverable. I want Exim to be able to refuse delivery at
the gateway when first receiving it. Exchange can be configured to use
VRFY, so I wanted an option to make it configurable for cases such as this.
When talking to Exchange, RCPT doesn't tell you anything useful.
