procmail, cyrdeliver, mailbox names

[brian]

cyrus-imapd 2.2.13-14ubuntu3

This doesn't only concern Cyrus but please bear with me. I believe my 
final hurdle does specifically involve cyrus.

I'm trying to get procmail to send SPAM to Junk folders for virtual 
users. I have it set up to use cyrdeliver for that. I feel like I'm 
almost there but I haven't been able to figure out precisely how to pass 
the mailbox name.

These are all virtual users, so I can't use $HOME in procmailrc. For the 
example below, the mailbox is at:

/var/spool/cyrus/mail/domain/f/foo.org/b/user/bally

This was giving me headaches with procmail until i realised that I could 
have it pass the job to cyrdeliver, which I expected would know to do 
the right thing. However, it looks like I'm not passing it the correct 
info to do so. I keep getting "Mailbox does not exist" errors because of 
the way that cyrdeliver expects the mailbox name.

Additionally, the account login names are the complete email address.

I should mention that everything--including Spamassassin--is otherwise 
working properly.

Some other things I've tried (in master.cf):

-m USER=${original_recipient}

verify_user(foo.org.junk!bally) failed: Mailbox does not exist

.. and, in procmailrc:

:0
* ^X-Spam-Flag: YES
| /usr/sbin/cyrdeliver -a $USER -m user.$USER.junk

:0
| /usr/sbin/cyrdeliver -a $USER -m user.$USER

verify_user(foo.org.junk!user.bally) failed: Mailbox does not exist


What's the format that cyrdeliver expects, given my mailbox setup?


Finally, the actual users' junk box is named, "Junk". I renamed my test 
user's because I noticed that cyrdeliver seemed to be folding the 
mailbox name to lowercase (though I'm not passing -u). Renaming didn't 
seem to help but I'm a bit confused. In imapd.conf, I have 
lmtp_downcase_rcpt: yes, but this is the mailbox name, not the 
recipient, so I'm not sure if this is the reason. What I can do about 
this, short of having all the users rename their Junk folders?

I also have unixhierarchysep: no, in case that's relevant to the above.
