CEF has the SMTP engine developed by Cellopoint. In addition that the implantation of relay mode is supported in general anti-spam products, the implantation of transparent mode is also supported by CEF.

Most anti-spam mail products in the market apply mail handling software package (open source), and thus the SMTP connections can not be adroitly used and handled. Cellopoint considers that the SMTP connection handling engine must be developed by ourselves in order to effectively handle enormous SMTP connections. The SMTP handling engine developed by Cellopoint can intercept mails sent through SMTP connections for mail inspection. The mails which fail the inspection checks will be intercepted or quarantined, and they will thus not be sent to mail relay host as a result of that the burden of the mail relay host can be significantly reduced.

CEF supports Fault Tolerance and Redundant Solution. It can continually provide the services of email management and anti-Spam, as well as the Active-Active Load Balancing service for multiple CEFs, and also integrate easily with customers' existing Layer 4 Switch.
