Hello,

This a Maildrop,Postfix MTA,Courier IMAP question.

I am using the Postfix local delivery agent with Maildrop.

I am currently using kernel quotas for virtual users.

It has caused some problems, so I am now testing maildrop with deliverquota on another server.

I have read through a lot of different documentation and I am getting confused. Where does the deliverquota command spawn ? Does this command come from the MTA or the the Courier IMAP server ?

I have maildrop quotas style working on my test machine, but the quota warning messages are not being generated when I log in.

For example, I went over quota yesterday. I never got a quota warning, which usually creates a tiny file telling Courier that a warning message was sent.

See maildrop quotas work... ;-)

Mar 3 15:27:05 annapolislinux postfix/local[29995]: C158314837: to=<tj...@annapolislinux.org>, relay=local, delay=0, status=bounced (permission denied. Command output: Mail quota exceeded. )

I raised them. tjk@annapolislinux:~/Maildir$ maildirmake.courier -q 2000000S ../Maildir

My /etc/courier/maildroprc file looks like this it should be send me a warning message at 65 percent:

cat /etc/courier/maildroprc

MAILBOX="$HOME/Maildir" MAILDIRQUOTA="$MAILBOX/maildirsize" "| /usr/bin/deliverquota -w 65 $MAILBOX"

I also have courier using authldaprc where it poles a number for the mailqouta off the local ldap server. This number may be different.

In my Postfix main.cf I have this parameter which is working. mailbox_command = /usr/bin/maildrop -d "$USER"
