B. Courier-Maildrop-2.0.3

remark uid / gid 505 = UID & GID of /home/vmail

then I cp maildrop/maildirmake from /usr/local/maildrop/bin/maildrop to /usr/bin , also rename maildirmake as maildirmake.courier chown root:vmail /usr/bin/maildrop chmod u+s /usr/bin/maildrop

~~~~~~~~ Problems I need help ~~~~~~~~~~~~~ I found that once the users maildir over 1.9M OR near around 2M . quotawarnmsg didn't sent out . IF the mailbox over 2M . Sender can't send e-mail to that " 2M " quota mailbox anymore . At the same time " Sender " willing get a return mail notice that mailbox is overquota already .

I had been set every users maildir quota as 2M , inside /etc/postfix/main.cf I did the following config as well .

maildrop unix - n n - - pipe flags=Rhu user=vmail argv=/usr/bin/maildrop -w 90 -d ${recipient}

Then I create quotawarnmsg in /usr/local/etc/quotawarnmsg . I put quotawarnmsg since i aware that there have a " echo " while I " make install " maidrop

echo '#define QUOTAWARNMSG "/usr/local/maildrop/etc/quotawarnmsg"'

I also make quotawarnmsg as world readable .

For maildroprc , I also put this config inside .

logfile "/var/log/maildrop.log" `test -e $DEFAULT` if ( $RETURNCODE != 0 ) { `/bin/mkdir -p $DEFAULT` `/bin/rmdir $DEFAULT` `/usr/bin/maildirmake.courier $DEFAULT` }

I would like to know is there any point missing ?

Since I search around google for few days already . But I still found that the problems still remain .

Thanks .
