dovecot - Jul 2009 - Expunged emails getting automatically deleted

Hello,

	So i had this email in my inbox, i moved it to Folder1/tickets/   
folder, then i decided to move the same email back to my inbox and  
when i went to the inbox it wasnt there nor in Folder1/tickets/  
folder...

	I opened a SSH session to the mail server and went to /srv/mail/ 
vmail/DOMAIN.COM/rventura/Maildir

	There i did "ll expunged/.INBOX/cur" and it showed me 300+ emails i  
then did "cat expunged/.INBOX/cur/the email i needed" and it showed  
me the email contents and since it was the one i needed i then try to  
do "mv expunged/.INBOX/cur/email-id" and it returned:
mv: cannot stat `expunged/.INBOX/cur/ 
1248796845.M207411P29102.housigma20,W=6193:2,STab': No such file or  
directory

I do another "ll expunged/.INBOX/cur/" returns total 0.....  WTF  
happened to all my items..?

My guess: Your IMAP client opened the .EXPUNGED/INBOX mailbox and
expunged messages in them (some auto-expunge feature?).

It probably just crossed over the rounding threshold.

You probably don't want to access these mailboxes all the time? Try
setting all of them to list=no. That makes sure it's not your IMAP
client that's losing your mails..

Also this change from v1.2.2 would probably help too:
