[Dovecot] dovecot overquota and delete message

[sa]

Hi all,

i use dovecot-1.1_rc1 with postfix and maildrop as deliver. The problem is
where user gets overquota, at this point he is unable to delete message in
pop3 as imap.

dovecot.conf has:

plugin { 
    quota = maildir 
} 
protocol imap { 
  mail_plugins = quota imap_quota 
} 
protocol pop3 { 
  mail_plugins = quota 
} 

I change it to

plugin { 
    quota = maildir:ignore=Trash 
} 

and 

plugin { 
    quota = maildir:storage=100240:ignore=Trash 
} 

but the problem persist.

I have to del manually maildirsize file to get the user back to delete.

Any suggestion ?

tnx

s
