I've been using p0f for a while (> 1 year I think) with no problems. p0f runs
"passively" and then Exim queries it via a ${perl expansion (though I suppose
if I wanted to I could write a kind of exim-to-p0f proxy and use a plain
${readsocket instead).
Currently all I'm doing with it is querying p0f from exim and logging the
results - the results don't actually /affect/ anything (except the contents of
the log). But to that extent, it works just fine.
