Weird.  In the MUA I was seeing this:

C: 4 LIST "" (INBOX IN.dovecot) RETURN (STATUS (UNSEEN))
S: * LIST () "." "IN.dovecot"
S: * STATUS "IN.dovecot" (UNSEEN 0)
S: * LIST () "." "INBOX"
S: * STATUS "INBOX" (UNSEEN 1)
S: 4 OK List completed.


Then I did this:

slusarz at bigworm % dovecot
* PREAUTH [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID  
ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS  
MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED  
I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN  
CONTEXT=SEARCH LIST-STATUS SEARCH=FUZZY SPECIAL-USE ACL RIGHTS=texk]  
Logged in as slusarz
1 LIST "" (INBOX IN.dovecot) RETURN (STATUS (UNSEEN))
* LIST () "." "IN.dovecot"
* STATUS "IN.dovecot" (UNSEEN 7)
* LIST () "." "INBOX"
* STATUS "INBOX" (UNSEEN 1)
1 OK List completed.


Sure enough, I went back to the MUA and now see this:

C: 4 LIST "" (INBOX IN.dovecot) RETURN (STATUS (UNSEEN))
S: * LIST () "." "IN.dovecot"
S: * STATUS "IN.dovecot" (UNSEEN 7)
S: * LIST () "." "INBOX"
S: * STATUS "INBOX" (UNSEEN 1)
S: 4 OK List completed.


The only difference... in the MUA I am enabling QRESYNC.  This is what  
the previous commands look like (before reaching the LIST-STATUS  
command):

>> Timestamp: Fri, 02 Mar 2012 11:17:56 -0700
S: * OK [CAPABILITY IMAP4rev1 LITERAL+ LOGIN-REFERRALS ID ENABLE  
AUTH=LOGIN XIMAPPROXY] Dovecot ready.
C: [LOGIN Command - username: slusarz]
S: 1 OK User logged in
C: 2 ENABLE QRESYNC
S: * ENABLED QRESYNC
S: 2 OK Enabled.
C: 3 STATUS IN.horde.cvs (MESSAGES UIDNEXT UIDVALIDITY HIGHESTMODSEQ)
S: * STATUS "IN.horde.cvs" (MESSAGES 11 UIDNEXT 16767 UIDVALIDITY  
1239077891 HIGHESTMODSEQ 31409)
S: 3 OK Status completed.


Next time I see this issue, I will try to go back and issue ENABLE  
QRESYNC from the command line.

Nothing fancy: jfs on Archlinux.  I've been using it for years - it's  
not something I have recently changed.
