OK, I'll give the trace a try. Thanks for the instructions.

In the meantime, here is more info.
The sieve script does a redirect and a local save. It works fine if only
the redirect is in place.

if true {
    redirect "some.email at domain.com";
}

if true {
    keep;
    stop;
}

I'm using mdbox as storage.

Cheers,

Olivier
