OK, thanks.

One more question: can I somehow refer to the shared folder in the global sieve
script? That is, is there a variable that contains the left part of the
destination address, or, more precisely, the name of the folder that comes
after the '+' in a destination address such as

  bb+testbb at mappi.helsinki.fi

? I'd like to file the message tagged as spam into a subfolder of the shared
folder, something like this:

--clip--
if allof (header :matches  "X-HY-Spam-Status" "***") {
     fileinto "<shared folder>.junk";
}
--clip--

Or would I have to either create a sieve script for each shared folder (that
receives mail) or just filter all spam to any shared folder in one global spam
folder?

Thanks,
