I don?t think that will work.  My MTA is postfix and it?s connected to dovecot
via LMTP, so AFAIK postfix is talking to dovecot over a socket, and dovecot-lda
isn?t being invoked so there is no place to pass that the -m parameter.  But we
are at the limits of my understanding of how all this stuff actually works under
the hood so please correct me if I?m wrong here.

Ah, you are using LMTP... then the easiest is to use Sieve here. 

You can use simple global script, e.g. /etc/dovecot/default-mbox.sieve

```
require ["fileinto", "mailbox"];
fileinto "OtherBox";
```

then sievec the script, and use

plugin {
  sieve_before = /etc/dovecot/default-mbox.sieve
}

this way it will change the default mailbox, but allows per-user scripts to
change it.
