Hello everyone, I face the following challenge: - dovecot 2.2.13 - userdb: passwd-file - quota enabled: -- default 1GB -- changed for some users thru users file: user at domain:passwd::::::userdb_quota_rule=*:storage=15M - when sending a message to this user while near quota, warnings are correctly triggered => *OK* - when sending a message to this user while over quota, message is refused => *OK* - when checking quota from mail client (eg Thunderbird 45.2), reported quota is.. 1GB => *NOK* - some config: mail_plugins = quota notify acl plugin { acl_shared_dict = file:/sd/MAIL_IMAP_POP/%d/shared-mailboxes quota = maildir:User quota:ns quota_exceeded_message = Storage quota for this account has been exceeded, please try again later. quota_rule = *:storage=1G quota_rule2 = Trash:storage=+10%% quota_rule3 = Spam:storage=+20%% quota_status_nouser = DUNNO quota_status_overquota = 552 5.2.2 Mailbox is full quota_status_success = DUNNO quota_warning = storage=90%% quota-warning 90 %u %d quota_warning2 = storage=75%% quota-warning 75 %u %d } protocol imap { mail_plugins = quota notify acl imap_quota imap_acl service replication-notify-fifo { name = aggregator } service anvil-auth-penalty { name = anvil } service auth-worker { name = auth-worker } service auth-client { name = auth } service config { name = config } service dict { name = dict } service login/proxy-notify { name = director } service dns-client { name = dns_client } service doveadm-server { name = doveadm } service imap { name = imap-login } service imap-urlauth { name = imap-urlauth-login } service imap-urlauth-worker { name = imap-urlauth-worker } service token-login/imap-urlauth { name = imap-urlauth } service login/imap { name = imap } service indexer-worker { name = indexer-worker } service indexer { name = indexer } service ipc { name = ipc } service lmtp { name = lmtp } service log-errors { name = log } service pop3 { name = pop3-login } service login/pop3 { name = pop3 } service replicator-doveadm { name = replicator } service login/ssl-params { name = ssl-params } service stats-mail { name = stats } } - 90-quota: passdb { driver = passwd-file args = scheme=CRYPT username_format=%u /etc/dovecot/users } userdb { driver = passwd-file args = username_format=%u /etc/dovecot/users # Default fields that can be overridden by passwd-file #default_fields = quota_rule=*:storage=1G # Override fields from passwd-file #override_fields = home=/home/virtual/%u } Any idea? Already spent hours on this. Thank you in advance for the help. Cheers A.
