Is BorderWares SMTP gateway secure?
The mail system was originally designed from the start with a security model in mind. In addition, the system consists of independent programs to do SMTP reception, routing decisions, SMTP delivery, and delivery scheduling among others. It is based on ZMailer, a mature mail system in use on major Internet gateways. The author of ZMailer made further specific enhancements for the BorderWare product. ZMailer has no code relation to Sendmail and has not been susceptible to any of the security problems associated with Sendmail. ZMailer runs without special privileges in an isolated environment (as do all the servers that run on BorderWare).
