deliver to mailbox folder not working

[Vernon A. Fort]

I have a script that re-delivers email messages from one mailbox to 
another.  The following worked with 2.3.13 but does NOT work with 2.3.14

/usr/lib/cyrus/deliver -a testuser -m user.testuser.subfolder < email.txt

All i get is mailbox does not exist and a "lmtpunix: 
verify_user(user.textuser.subfolder) failed: Mailbox does not exist.  
All the acl are correct - set to 'all' on both the inbox and subfolder.  
The message IS a valid email message and again, the deliver command 
worked with the previous version.  I'm using gentoo and they removed the 
2.3.13 version from portage.  Has the command syntax changes....
