[Dovecot] Folders mysterously deleted

[Andy Cravens]

Using alpha 3 on Solaris 9.  One of our users reported all folders 
except his inbox were missing.  I went to the server and looked at the 
logs and could find no indication that a sysadmin had logged in and 
deleted the folders.  Also found no indication of anything unusual in 
the dovecot log file.  Has anybody seen a situation where dovecot 
deleted folders?
