    Go on, have a guess
    Teergubing (or tar pits) are a good idea in theory, but in practice I've seen them cause serious problems on busy mail servers. Because you keep an SMTP connection open for a long period of time, you're consuming resources in your server (i.e. memory) and taking up an SMTP connection. It only takes a distributed dictionary attack for all the SMTP connections to get tied up, your server performance sufferes because of memory problems and no-one can send or receive email as exim can no longer answer SMTP connection requests.

    I have played with it, but it ends up causing more problems than it tries to solve, IMX.
