yes, on the delivering server if your configuration is mysql-based and mysqld is down your server must not accept messages because missing the list of valid RCPT a replication slave would be a good idea so you can receive the messages even if your backends are a mysql storage because the received messages will be deferred in this case locally and the sender gets a 250 OK
