Edit: Psoasman, it sounds like both of those reside on the same LAN.
Technically, wouldn't it be neither as the question doesn't specify that the email server is ipsec enabled? Or if the the server isn't ipsec enabled, it would have to be be tunnel mode as the server would not be on the same network as the client and the secured traffic would have to be between the client and an ipsec gateway on the private network containing the email server?
