i am currently using roundcube my webmail and configure using dovecot quota plugins. but it seems to not be updating the maildirsize when new mails comes.Deleting the maildirsize will recreate the files correctly.Is there any solutions to this problem with dovecot.

Either you're not using dovecot-lda to deliver the mails, or you haven't configured quota plugin correctly for it. dovecot -n output and logs about a mail delivery would help.

My configuration is using Centos 6.dovecot 2.1.1.and i have configure the quota plugin.but i am not sure what you mean by dovecot-lda.i just follow the guides on the internet and skim through dovecots documentation.i am using the local unix account for mail account not using virtual users.here is my configuration:

[root@mail ~]# dovecot -n

2.1.1: /etc/dovecot/dovecot.conf

OS: Linux 2.6.32-279.el6.x86_64 x86_64 CentOS release 6.3 (Final)

base_dir = /var/run/dovecot/ mail_debug = yes mail_location = maildir:~/Maildir mail_plugins = " quota" maildir_broken_filename_sizes = yes mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } plugin { quota = maildir:User quota quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_id_log = * imap_idle_notify_interval = 2 mins mail_plugins = " quota imap_quota" } protocol pop3 { mail_plugins = " quota imap_quota" }

i am still not sure why maildirsize is not updating.thanks
