Note that the SMTP error code is "450", which is a retryable error;
it is not a permanent error. The domain
slayers.org
may be one that does not exist, or it may be that at the time the mail
is queued, the relevant name servers are offline or misconfigured
so that the MTA cannot tell if the domain really exists. The MTA and
Mailman cannot be sure. In this case, the MTA will keep trying for the
"queue length" time in its configuration file.
