You may recall my blog post last month, “Managing Email in the Cloud” in which I described how enterprise customers are embracing cloud computing for inbound email filtering. I shared more thoughts on the subject recently with a reporter from E-Commerce Times for an article.

Here is an excerpt from the article that was published today.
Security: E-Mail in the Cloud
Commodity applications like in-bound e-mail filtering — such as antispam and antivirus applications — can be handled outside an enterprise internal IT infrastructure and are well-suited for the cloud, suggested Glen D. Vondrick, EVP and COO of Sendmail.
“However, global organizations who rely upon e-mail as a mission-critical business application cannot move the e-mail backbone to cloud computing because of the requirements for guaranteed message delivery to the right mailbox,” he told the E-Commerce Times.
Once a message is “cleansed” in the cloud and deemed ready for delivery, a modern message processing infrastructure is required to route the message according to centrally controlled requirements based on message content, recipient location or classification, or corporate governance policy, Vondrick explained.
This is not easy to do in a cloud environment — especially for enterprises that have multiple e-mail gateways in various locations; have various e-mail domain names due to mergers and acquisitions; engage in high-volume marketing promotions; or are concerned with preventing data leaks in outbound e-mail.
Companies with those particular circumstances might want to investigate a hybrid architecture that integrates low-value commodity applications in the cloud with an on-premise modern message processing infrastructure.
