Remote Email Filtering
In 2006, Aptivate was commissioned by INASP to write a report on the effects of Remote Email Filtering. The report is based on our experience of working with African universities to identify the effects of passing their incoming email traffic through a remote third-party spam filtering service. The results indicated that using a filtering service is cost-effective in improving available bandwidth, particularly when used in conjunction with webmail blocking. It also provides other benefits such as reduced load on servers, and reduced network admin time overheads.
