Dear Sir,

I installed Postfix+Courier-Imap+Maildrop, I am using virtual MBOX and Non-unix
system account on Postfix.

Courier-Imap and Maildrop installed at /usr/local/courier/ I copy /usr/local/courier/etc/quotawarnmsg.example to
/usr/local/courier/quotawarnmsg.

I made maildirmake && maildirmake with option -q 1000000S to assign quota 1MB
for all Maildir.

When quota is over or I send an attachment bigger then 1MB, but system did not
send any warning.

I checked: #cat /home/virtual/test.com/info/Maildir/maildirsize 1000000S 2407211 1 -2407211 -1

Please support me about:

1) How to activate maildrop to notify when overquota ? ( I configure maildrop --enable-quota --with-trashquota, #/etc/postfix/main.cf mailbox_command = /usr/local/courier/bin/maildrop -w 90 virtual_transport = virtual #/etc/postfix/master.cf maildrop unix - n n - - pipe flags=DRhu user=vmail argv=/usr/local/courier/bin/maildrop -d
${recipient}

Is maildrop ready active ? )

2) How to trap error code when overquota to do bounce and reject message to
sender ?

3) If I use .mailfilter to do, how do I enable it and scripts to get overquota
code?
