Campus implements new spam-blocking system
Starting on Tuesday, October 19, after 11 p.m., the campus
implementing a new spam-blocking system known as "SBL/XBL
blocking" for all incoming "@ucsc.edu" email.
This system, which the School of Engineering and Physical and
Sciences have already been using, checks all incoming "@ucsc.edu"
messages against a list of known spammers and rejects any message
that comes from a server known to send large amounts of spam.
This approach blocks spam "at the front door" and
doesn't allow it into
the system, which has, in the past, resulted in wasted user
space, and processing power.
When a message is rejected, the sender will receive a bounce
message. Spammers will ignore these messages, but legitimate
senders will know that they need to try sending email to you
from another address or that they need to contact their Internet
Service Provider (ISP).
This system is one that has been proven to have a very low
"false positive" errors. In addition, this system
is expected to reduce significantly the load on the campus mail
The use of the SBL/XBL spam-blocking system has been approved
by the CruzMail Steering Committee, the Information Technology
Committee (ITC), the Committee on Computing and Telecommunications
(CCT), the Executive Advisory Committee (EAC), and ITS management.
