For a short period from 14:00 to 14:15, mail.heanet.ie rejected incoming
SMTP connections due to a high number of simultaneous connections.
Mail to customers using mail.heanet.ie for primary or secondary MX service
will have been delayed.
20041013 14:14 BB Investigated source of the high number of SMTP
connections - turned out to be a spam robot in Indonesia. Put a temporary
filter on mail.heanet.ie to block inbound connections from this source,
and restarte the mail service. So far, service has returned to normal.
Will continue to monitor for load spikes.
