[Dovecot] failed: Message has been copied too many times

[Angel L. Mateo]

Hello,

	I'm running dovecot 2.1.16 in a ubuntu 12.04 server, with lazy_expunge, 
SiS and mdbox format.

	The problem I'm having is that the index for one the mailboxes of one 
of my users is growing too much. This is not the first time of this 
problem. In previous cases, is because a message is duplicated thousand 
of times (I haven't found any reason for this). In these cases, moving 
messages to other folder and moving again to this same folder fixes the 
problem. So I have tried this, and I have moved all messages from this 
folder to another one.

	But this time, after this, indexes directory is still using a lot of 
space. And the folder seems to have more serious problems:

amateo_adm at myotis51:~$ sudo doveadm search -u vlo  mailbox 
BORRADOS.INBOX.MNCS
doveadm(vlo): Error: Syncing mailbox BORRADOS.INBOX.MNCS failed: Message 
has been copied too many times (59306 + -1)

	I have tried to delete the folder, with the same result:

amateo_adm at myotis51:~$ sudo doveadm mailbox delete -u vlo 
BORRADOS.INBOX.MNCS
doveadm(vlo): Error: Can't delete mailbox BORRADOS.INBOX.MNCS: Message 
has been copied too many times (59306 + -1)

	And to purge user's mailbox, but it didn't fix the problem.

PS: If this could help, BORRADOS. is the namespace used by lazy_expunge 
plugin.
