Do not rely on switches because switches are not designed for security.Based on that logic, there's just about nothing you CAN rely on, except death, taxes, and sendmail bugs.I don't think that's very fair. It seems obvious to me that some systems have more attention paid to them for security (VMailer, for instance) than others (like Sendmail). My confidence in VMailer is much greater than my confidence in Sendmail, to the point where I'd be willing to consider deploying VMailer in circumstances where Sendmail's lack of reliability is prohibitive. Same goes for switches and link-layer security.
Even more unfair... I agree with you regarding Vmailer/sendmail but I would compare sendmail = hub and vmailer = switch. The former has little security in it (let's assume that a hub is a very bugged switch) while the latter has more security. Vmailer/switch are not secure enough to use them alone for security, you used them with other devices, don't you ? I stop here because, the smell of religious war is becoming apparent -eric
