I had this problem, on IMAP, too and it was because of an error with the 
dictionary service. I was getting repeated mails from this list, using 
Dovecot as the LDA. The dictionary service problem was on dovecot 1.2.13 
and was an error on Timio's part. He is suppose to patch it in 1.2.14, 
if I understood him correctly.  When I disabled all dictionary services, 
dovecot worked perfectly.

The disabling was not a problem for me and can be worked around for 
being required for quota or expire by using a script for expire and 
doing quota by Maildir. If you use dbox or mbox, you'll need the 
dictionary service.

Make sure you have no errors in your log.
