Effective 16 September 2014, SDSC's incoming mail service is provided by the UCSD campus IT department rather than SDSC's own server. The UCSD mail logs are not currently available as a source of data for this survey, so there is nothing to report. Links to older survey results are on the Blacklists Compared page. Apologies for the inconvenience. This document was last updated by Jeff Makey <jeff@
