Hi Evren,

Please don't send any reply to me privately unless explicitely
requested. I do read the list (else I wouldn't have been able to answer
your question) and I don't need two or more copies of one mail.
Thank you.

What about an extra partition for '/var/qmail/queue' that's simply
mounted there? No need for symlinking, lots of space, not affected by a
possible overflow in '/var/log', etc , etc ...

Stop the SMTPD for no new mails coming in. Make your best attempt to
stop processes that might inject mails locally.
Send 'qmail-send' process an 'ALRM' signal. Wait.

You'll /NOT/ loose any external mail that can't be delivered due to the
fact the SMTP is down, /IF/ the foreing MTAs are configured correctly.
They should keep the message "in queue" for several days until your MTA
is up again (if you don't even have a backup MX for your domain).

Maybe because 'qmail-send' still ran when you did something on this
file? It's 'fifo', a 'name pipe' and qmail-send keeps a handle opened on
this file. Stop qmail-send before moving anything and if you've any
trouble moving 'lock/trigger' "as is" use 'mkfifo' to recreate it at
it's new location.

'make setup' in qmail source tree will generate the queue structure.

But you can easliy

pushd /var/qmail/queue
find . -type d | \
(cd /path/to/new/queue/dir; 
while read $DIRECTORY; do mkdir "$DIRECTORY" && \
chown --reference=/var/qmail/queue/$DIRECTORY && \
chmod --reference=/var/qmail/queue/$DIRETORY ;

It's then two files to copy: './lock/{sendmutex,tcpto}' and the fifo
'./lock/trigger' that has to be created and you're done with creating a
new, clean qmail-queue-structure.
