Have you looked at sauce? It's written by Ian Jackson (in TCL!) and
is intended as a front-end to exim. I'm not using it but I am looking
at the code for some ideas for a system I'm working on. It's not
exactly user friendly but it didn't look impossible to set up.
Not a debian package: ucspi-tcp by DJB includes "rblsmtpd" which can
be used as a teergrube. It will reject messages with "451" until a
timeout. The timeout is 60 seconds by default but you can configure
it.
BTW, isn't the word "teergruße" rather than "teergrube"? That's a
german double S for those who can't read it ...
