Hello, We recently switched from open source packages (Sendmail, Spamassassin, Mimedefang, Clamav) to Cisco IronPort Appliances. The appliances were fairly expensive but have greatly reduced the amount of spam and phishing that gets through. Comparing the effectiveness of the open source mail gateways to the Iron Port, the amount of spam getting through has dropped by approximately half.

We have also been extremely pleased with all of the functionality and features that the IronPorts have out of the box. If anyone has any specific questions feel free to contact me either directly or through the mailing list. Thanks. -Josh Flaherty From: The EDUCAUSE Security Constituent Group Listserv [mailto:SECURITY () LISTSERV EDUCAUSE EDU] On Behalf Of David James Anderson Sent: Tuesday, June 11, 2013 10:56 AM To: SECURITY () LISTSERV EDUCAUSE EDU Subject: [SECURITY] Phishing, Spam Solutions Good Morning, We are looking to reduce the number of phishing emails getting to our users' inbox. We currently have a homebrew filter of sorts and were wondering what is out there in the free and commercial worlds. We're envisioning a software that keeps itself up-to-date with a global list somewhere, but also has the functionality of allowing us to add custom rules for phishes specific to us. What tools do you use and what would you recommend to others? -- -David. David Anderson Information Security Analyst, Senior Information Technology Systems Northern Arizona University (928) 523-1225
