An earlier delivery attempt to this address failed with a temporary deferal. When a delivery attempt to an address fails with a temporary error, Courier will reject all subsequent messages to this address accordingly, until the original message gets succesfully delivered.
Look in the mailq and find a pending message that's waiting to be delivered to this account. Get its message id and grep the mail logs to figure out why this message cannot be delivered. Fix it, and after the message gets successfully delivered to this address, Courier will resuming receiving more mail to this address.
If you don't find anything in the mail queue, grep the mail logs for the first delivery error to this address.
