Procmail and munpack problem : could not get current directory

Hello

Some time ago I got here an advice how to list all mail attachments. It was
from Gary Funck and he advised me to use this :

:0
* ^Content-Type:[       ]*multipart/mixed
{

TMPDIR=`mktemp -d munpack-XXXXXX`
TRAP="rm -rf $TMPDIR; $TRAP"

:0
ATTACH_INFO=|munpack -C $TMPDIR -q

#Now, do something with $ATTACH_INFO

}


As I am using AIX 4.3.2, so I have no mktemp command and also had to compile
munpack by myself. That's what I did in /etc/procmailrc (no drop of
privileges are configured, procmail is suid root)  :

MUNPACK=/usr/local/procmail/bin/munpack
TMPDIR=/tmp/procmail.$$

:0 Wic
 | mkdir -p $TMPDIR

 FLIST  = `$MUNPACK -q -t -C $TMPDIR  2>/dev/null`

Now sometimes (not every time!) I am getting this message :

procmail: Assigning "MUNPACK=/usr/local/procmail/bin/munpack"
procmail: Assigning "TMPDIR=/tmp/procmail.36688"
procmail: Executing "mkdir,-p,/tmp/procmail.36688"
procmail: [36688] Thu Mar 18 09:16:41 2004
procmail: Assigning "LASTFOLDER=mkdir -p /tmp/procmail.36688"
procmail: Executing "cd $TMPDIR; $MUNPACK -q -t -C $TMPDIR  2>/dev/null"
shell-init: could not get current directory: getcwd: cannot access parent
directories: Permission denied
cd_links: could not get current directory: getcwd: cannot access parent

/usr/local/bin/bash: cd: /tmp/procmail.36688: Permission denied
job-working-directory: could not get current directory: getcwd: cannot
access parent directories: Permission denied
procmail: Assigning "FLIST="

Why this error occurs sometimes ?

Thanks everyone for tips and advises.


With best regards
Martynas
