Setup is based on Andrew Koros': Postfix+Cyrus+PostgreSQL+Web-cyradm+RedHat

My ver of cyrus is listed at bottom of this post.

I am in a bind due to a disk gone corrupt on our RAID5 array. We had to 
fsck the filesystems.  Most mailboxes and users are now working fine 
again after doing some reconstructs.  However, there are a few critical 
issues that I cannot seem to fix.  Here is what I have done:

(As Cyrus User)
/usr/lib/cyrus-imapd/reconstruct user/

Reconstruct seemed to work for the most part.  I can now successfully 
login via IMAP with this user account.  I can download and read 
messages, etc.

HOWEVER, when trying to SEND messages to these user accounts I am 
getting one of the following two error messages (different for each 

delay=1382, status=deferred (host public/lmtp[public/lmtp] said: 451 
4.2.0 Mailbox has an invalid format (in reply to RCPT TO command))

relay=public/lmtp[public/lmtp], delay=1705, status=deferred (host 
public/lmtp[public/lmtp] said: 451 4.3.0 System I/O error (in reply to 
RCPT TO command))

Thanks very much for any help or ideas!

Kind regards,
