As exim gets a temporary error for "RCPT TO", it thinks the mailbox is currently not available. Exim can't know that another e-mail in the queue with a different sender address could actually get through to the recipient. With a moronic greylisting setup (no auto-whitelisting) on the remote side and a lot of emails this really is a problem. One may choose at which side the problem is, though.
Is Exim designed to be clever, and not to attempt to deliver further
messages to the same recipient? I thought it was just for hosts that
were down, but I wonder if there's an option to disable this cleverness
if it's not compatible with greylisting at remote sites.
