Today on the Datanauts it’s email security. Lots of organizations have outsourced their email to the cloud, and for good reasons: Web access is ubiquitous, email infrastructure can be a pain to manage and secure, and email can take up lots of storage.

But there are also good reasons for keeping email in-house, including privacy and retention requirements, specific security needs, and the ability to maintain control over your infrastructure destiny.

On today’s episode we’ll discuss how to build a robust and secure in-house email infrastructure, talk about the importance of IPv4 and IPv6 support, explore technologies and protocols to validate email servers and thwart spammers, and explain the role of DNS in supporting secure email.

Our guest is Jacob Evans, Sr. Systems Engineer at WebstaurantStore.com. You can follow him on Twitter and check out his blog at www.jacobdevans.com.
