In Testing:

Note that the warning is ONLY executed at the exact time when the limit is being crossed, so when you're testing it you have to do it by crossing the limit by saving a new mail. If something else besides Dovecot updates quota so that the limit is crossed, the warning is never executed.

No warning mail was sent, at any point, even when the last mail was received, which exceeded the quota. That log was from pop3, not from mail delivery.. It's too late by then to give any kind of warnings. run correctly? (Note that I am forced to set (in Postfix) virtual_mailbox_limit = 0, because the max acceptable value of this parameter is 2G and in Dovecot I define mailbox limits of 4G. I haven't yet set any VDA parameters.) Postfix completely ignores quotas limits, warnings and everything else you've set in Dovecot! be using Dovecot LDA. http://wiki.dovecot.org/LDA [1]

Also, as my virtual mail user:group is vmail:vmail, should I change permissions in auth-master path (/var/run/dovecot)?

# ls -la /var/run/dovecot/
total 28
drwxr-xr-x  3 root dovecot 4096 Feb 22 23:32 .
drwxr-xr-x 23 root root    4096 Feb 23 08:36 ..
srw-------  1 root root       0 Feb 22 23:32 auth-worker.7282
srwxrwxrwx  1 root root       0 Feb 16 18:01 dict-server
lrwxrwxrwx  1 root root      17 Feb 16 18:01 dovecot.conf ->
/etc/dovecot.conf
drwxr-x---  2 root dovecot 4096 Feb 22 23:32 login
-rw-------  1 root root       6 Feb 16 18:01 master.pid

and in /var/run:

...
drwxr-xr-x 3 root    dovecot  4096 Feb 22 23:32 dovecot
...

Should we change to 777 so that vmail user (under which deliver will be running) has access to the above locations? If so, could there be security implications?

Thanks, Nick

Obviously auth-master is a socket and created on the fly (?)

Having received no reply on this, and trying to find my way through, I came to the hypothesis that the mentioned line should go where we do userdb lookups:

So in /etc/dovecot-passdb-ldap.conf (which is identical to /etc/dovecot-usrdb-ldap.conf), we should add:

hosts = localhost tls = no base = ou=people, dc=example, dc=com scope = subtree ldap_version = 3 dn = uid=authenticate,ou=System,dc=example,dc=com dnpass = ************* auth_bind = yes user_filter = (uid=%u) pass_filter = (uid=%u) pass_attrs = uid=user,userPassword=password auth_bind_userdn = uid=%u,ou=people,dc=example,dc=com user_attrs = roomNumber=quota_rule=*:bytes=%$,uid=home=/home/vmail/%u deliver -f $FROM_ENVELOPE -d $DEST_USERNAME

So, we change the last line from: user_attrs = roomNumber=quota_rule=*:bytes=%$,uid=home=/home/vmail/%u to: user_attrs = roomNumber=quota_rule=*:bytes=%$,uid=home=/home/vmail/%u deliver -f $FROM_ENVELOPE -d $DEST_USERNAME

Is this correct?

If not, please can someone clarify where exactly "deliver -f $FROM_ENVELOPE -d $DEST_USERNAME" should be called (when we do userdb lookups over LDAP)???

Thanks, Nick

Also, the line:

should be put in the main ("root") part of dovecot.conf ?

Thanks Timo,

In the end, I figured things out.

Below are the changes to my initial configuration; now everything works fine.

Just a note about a detail which took me some time to sort out: In postfix master.cf, in LDA setup documentation, the suggested configuration is:

dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f ${sender} -d ${recipient}

However, in my case, the working solution uses {user} rather than {recipient}, as - at the end - we just use the username for mailbox delivery and {recipient} is inappropriate in this context. I feel that this scenario is not rare in postfix/dovecot/LDAP implementations.

Config file changes follow:

# /etc/postfix/main.cf

mailbox_command = /usr/lib/dovecot/deliver ... dovecot_destination_recipient_limit = 1 virtual_transport = dovecot

# /etc/postfix/master.cf

dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f ${sender} -d ${user}

# /etc/dovecot.conf

protocol lda { postmaster_address = postmaster@noa.gr sendmail_path = /usr/lib/sendmail auth_socket_path = /var/run/dovecot/auth-master log_path = info_log_path = mail_plugins = quota }

# /etc/dovecot.conf, in listen {...

master { path = /var/run/dovecot/auth-master mode = 0660 user = vmail group = vmail }

Thanks again, Nick
