I have this setup like that, although without the -f and -m options.
Anyway, it seems that postfix first tries to run deliver with
$recipient=joe+spam, and deliver happily creates a new mailbox 'joe
+spam'. Any idea how to solve this?

The postfix documentation says it first tries to deliver to 'joe+spam',
and then to 'joe'. I'm not sure why deliver just accepts the user+ext
name, and creates a new folder.
