failed to create spool file

[Debbie Finucane]

Setting up exim-4.14 I keep getting the following error, when non-root
users send mail. (and now for exim-4.20 as well)

Failed to create spool file /local/mail/exim/spool/input//19FgDe-0005uO-70-D: Permission denied

Having tried it with various configure files, I think its a permission
problem somewhere, but I can't figure out where.

I have exim set suid root with

lrwxrwxrwx 1 root 11 May 13 13:09 bin/exim -> exim-4.14-3
-rwsr-xr-x 1 root 885072 May 13 13:09 bin/exim-4.14-3

The exim root directory has
drwxr-xr-x 5 exim exim 512 May 13 21:05 .

Also spool set to exim

drwxr-x--- 8 exim exim 512 May 13 20:29 spool

spool/ containing
drwxr-x--- 2 exim exim 512 May 13 20:50 input
drwxr-x--- 2 exim exim 512 May 13 20:50 log
drwxr-x--- 2 exim exim 512 May 13 20:50 msglog

and the output of exim -bP exim_user exim_group is

exim_user = exim
exim_group = exim

Neither the mainlog or paniclog succeed in logging anything when this
happens which is why I think it must be a permission problem.

Its running on SunOS 5.8 and I've set no_verify.

However when the superuser sends the mail to a non privledged account

It gets the following
LOG: MAIN
<= ***@medulla.amtp.cam.ac.uk U=root P=local S=362
medulla:/local/mail/exim/spool/log 21:22:10$ LOG: MAIN PANIC DIE
unable to set gid=20 or uid=8181 (euid=822): local delivery to df224 <***@medulla.amtp.cam.ac.uk> transport=local_delivery
LOG: MAIN PANIC
failed to read delivery status for \0\***@medulla.amtp.cam.ac.uk from delivery subprocess
LOG: MAIN PANIC
appendfile transport process returned non-zero status 0x0100: exit code 1
LOG: MAIN
== ***@medulla.amtp.cam.ac.uk R=localuser T=local_delivery defer (-1)
LOG: MAIN
Frozen

which may or may not be related to the above.

I'd be grateful for any ideas on this,


Debbie

Well - what is the uid 822 and gid 20 on your system?

Anything on syslog?

My suspicion is that you have two different exim binaries installed, and
there is confusion over which one is being run when mail is sent.

Have you tried sending the messages directly from exim? That is, with
commands like

exim -d ***@medulla.amtp.cam.ac.uk
some message
.

? That will show debugging detail of what is going on.

I never thought of checking there and it provided the answer.

It has many messages with

"uid 822: setuid execution not allowed, dev=8800000007"

where 822 is my exim user.


I've removed the nosuid mount option from /local and now I can
send local emails from non-root users.


Thanks for your help.
