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
