***Please Distribute Widely*** In an effort to further limit the amount of spam being handled by the central email system (@yorku.ca), CNS has integrated DNSBL (DNS-based blackhole lists) into the current spam filtering solution. All emails identified as spam by this mechanism will be rejected by the York email system. Legitimate email servers will return a mail delivery error message to the sender. In the event that a legitimate email gets rejected incorrectly, please contact CNS Client Services at [log in to unmask] with the email address the mail was destined for (the To: field), the email address of the sender, the IP of the sender and the general time the email was sent (day and hour is sufficient). Questions or concerns about this note, should be directed to the CNS Helpdesk in the Computing Commons, William Small Centre, (voice: 416-736-5800, email: [log in to unmask]). CNS Announce
