Hi,

i want to migrate the following setup:

postfix / courier-{imap/s,pop3/s,authlib} / maildrop / mysql

I´m using the maildir format and quotas as well.

My target is the following setup:

postfix / dovecot / some sort of quota respecting lda / mysql

What i`ve done already:

SQL-Implementation for dovecot, login process and also sending mails via auth-userdb is already working. Quotas are read out from database and working.

Before i mention my problems while implementing, here is the config im using at this time:

# 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.14.14-gentoo x86_64 Gentoo Base System release 2.2 auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb auth_verbose = yes disable_plaintext_auth = no info_log_path = syslog login_log_format_elements = user=<%u> method=%m ip=%r mpid=%e mail_debug = yes mail_location = maildir:.maildir mail_plugins = quota namespace inbox { inbox = yes location = .maildir 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 = INBOX. separator = . } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { args = /etc/dovecot/dovecot-sql.conf.ext quota = maildir:User quota quota_rule = %u quota_rule2 = trash:storage=+150M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u } service auth { unix_listener /var/spool/postfix/private/auth { group = mail mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0660 user = postfix } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0666 user = postfix } } ssl_cert =

grep -v '^ *\(#.*\)\?$' dovecot-sql.conf.ext driver = mysql connect = host=127.0.0.1 dbname=postfix user=postfix password=thereisone default_pass_scheme = MD5-CRYPT password_query =
SELECT username, password
FROM mailbox WHERE username = '%u' user_query =
SELECT concat('/', home, user, '/', destinationname) AS home, uid, gid,
concat('*:storage=', round(quota / 1000 * 1.024)) AS quota_rule
FROM mailbox WHERE username = '%u'

Where user is the row where the admin-panel user is stored and username is the mbox-user.

My problem is the LDA, with dovecot-lda im having the uid / gid trouble and i really dont want to suid oder sudo it. dovecot-lmtp just gives me

status=deferred (host xx.xx[/var/run/dovecot/lmtp] said: 451 4.3.0 box@xx.xx Temporary internal error (in reply to end of DATA command))

Postfix virtual is working as well as maildrop, but no dovecot-implementation wants to, i also didnt find anything about the error above, except a bug in v2.2.2 and a google groups thread where users are just blaming each others for nothing ..

I want to use a dovecot lda/lmtp because the quota settings for trash-folders are very nice and reducing my support times but im stuck at getting one of the dovecot-LDAs to work.

Let me know if you need any additional information.

Any help is greatly appreciated!

-- Viele Grüße / Best regards
