IMAP/POP?
Which version of Cyrus SASL and IMAPd are you running?
What does your sasl configuration look like? (grep sasl /etc/imapd.conf)
What are you 'virtudomains' and 'defaultdomain' config items? Verify
that user and user at hub.org are not admin users.

If you suspect Outlook or Cyrus is mucking up the username, use a wire
level capture tool (with ssl/tls temporarily turned off) to find out
exactly who is at fault.
