Delete a mailbox called user/{user}/~

[Jean-Noel BOUVIER]

Hello all,

One of my users has got a strange mailbox, the name of the mailbox is "~".

 > lm user/{user}/*
user/{user}/~/Mail/Trash


I can not delete this mailbox or any of the sub-mailboxes :

 > dm user/{user}/\~/Mail/Trash
deletemailbox: System I/O error


Does anyone know how to get rid of this mailbox ?

NB : There is no "~" directory in /var/spool/imap/user/{user}/

Thanks for your help.
