Does BorderWares mail server have any relation to Sendmail?
The mailer has no code relation to Sendmail. It was designed from the start with a security policy in mind. Border’s mail system is based on ZMailer. The author made further specific enhancements for the BorderWare product which allow it to run without any special privileges. ZMailer is a mature mail system with a solid track record that has been running on many major Internet gateways. It has not been susceptible to any of the security problems that Sendmail has.
