     Smtpprox is smtp aware. That is how it gets its name. The answer to that
    roughly equates to: How long is a piece of string? It is completely
    dependant upon several factors, as well as the types of lookups|checks you
    will be doing for each mail. The only way you can get a more precise
    answer to that question is to set the system up and benchmark it. There is
    also another smtp proxy possibly worth checking:
