The IMAP ACL extension allows control of the "p" (post) flag to allow
mail delivery to a folder other than INBOX. The convention that the Cyrus
sendmail configuration uses is that mail to username+foo@cyrus will be
filed into user.<username>.foo if "p" rights are available, otherwise it
goes into INBOX (user.<username>).
