How to fix "delivery 1: deferral:
Sorry,_message_has_wrong_owner._(#4.3.5)/" qmail mail delivery
failure message
After a failed attempt to enable some wrapper scripts to enable
domain keys support in a qmail powered mail server my qmail
server suddenly stopped being able to normally send mail.
The exact error message which was logged in
/var/log/qmail/current was:
@400000004dd66fcc16a088ac delivery 1: deferral:
Sorry,_message_has_wrong_owner._(#4.3.5)/
This
qmail messed happened after I substituted
/var/qmail/bin/qmail-queue and
/var/qmail/bin/qmail-remote with two respective wrapper
shell scripts which were calling for the original
qmail-queue and
qmail-remote binaries under the names
qmail-queue.orig and
qmail-queue.orig
Restoring back
qmail-queue.orig to
/var/qmail/bin/qmail-queue and
qmail-remote.orig to
/var/qmain/bin/qmail-remote and restarting the mail server
broke my qmail install.
After a bunch of nerves trying to isolate what is causing the error
I found out that by mistake I forgot to copy the
qmail-queue
and
qmail-remote permissions and ownership.
Thus I had to check another qmail working installation's
permissions for both binaries and fix the permissions to be
equivalent to the permissions:
debian:~# ls -al /var/qmail/bin/qmail-remote
-rwx--x--x 1 root qmail 50464 2011-05-20 12:56
/var/qmail/bin/qmail-remote*
debian:~# ls -al /var/qmail/bin/qmail-queue
-rws--x--x 1 qmailq qmail 20392 2011-05-20 12:56
/var/qmail/bin/qmail-queue*
The exact chmod and chmod commands I issued to solve the shitty
issues were as follows:
First I fixed the qmail-queue and qmail-remote
ownership:
debian:~# chown qmailq:qmail /var/qmail/bin/qmail-queue
debian:~# chown root:qmail
/var/qmail/bin/qmail-remote
Second I set the proper file permissions:
# make the qmail-queue binary suid
debian:~# chmod u+s /var/qmail/bin/qmail-queue
debian:~# chmod 611 /var/qmail/bin/qmail-queue
debian:~# chmod 611 /var/qmail/bin/qmail-restart
Third and last I did a restart of the qmail server and tested it
sends properly
debian:~# /usr/bin/qmailctl stop
Stopping qmail...
qmail-send
qmail-smtpd
debian:~# /usr/bin/qmailctl start
Starting qmail
Finally to test that the qmail server qmail-queue was queing and
sending with qmail-remote I used the system mail command like
so:
debian:~# mail -s "test email" testuser@pc-freak.net
asdfafdsdf
.
Cc:
Afterwards the mail was properly received on my mail account
testuser@pc-freak.net immediately.
In my /var/log/qmail/current log file all seemed fine:
@400000004dd6702a2eb2b064 starting delivery 1: msg 85281596

@400000004dd6702b34cc8c54 end msg 85281596
The test mail was properly received on my mail account
testuser@pc-freak.net immediately.
It took me like half an hour to figure out what exactly is wrong
with the permissions in situations like this I really wanted to
change all my qmail installs with postfix and forget forever I ever
used qmail ...
