I was asked to try the same thing several weeks ago but was not informed of what it was accomplishing. Possibly someone could let us all know....

That seems to fare better. I still get the errors (more of them) when debugging (see output below), but the results are as expected. Spam is stored correctly and no crash.
Could you tell me what I've just done by adding the -U switch?
----------------------
[root at mail conf.d]# MailScanner
In Debugging mode, not forking...
Trying to setlogsock(unix)
Building a message batch to scan...
Have a batch of 1 message.

Stopping now as you are debugging me.

Vincent,
Try running MailScanner with the -U switch, as follows:
nano /usr/sbin/MailScanner
#!/usr/bin/perl -I/usr/lib/MailScanner -U

Distro is Scientific Linux 6.1 (another RHEL spinoff like CentOS)

What distro ?
I gave up on Ubuntu Natty. Switched to CENT6. I literally built 10 VMs and all had the same "16:48:22 Insecure dependency " that you are having, and caused the same thing. Yet no one else was able to duplicate my issue

Hi all,
I think I'm running into a permissions problem, but aren't sure and am a bit stumped...
When SA finds that an email is spam and MS (4.84.3) is told to "store", MS crashes. ("deliver" goes fine)
When running in debug mode, I can see that SA, ClamAV, are doing fine and these are the last few lines:
-------------
16:48:22 Sep 26 16:48:22.048 [19001] dbg: learn: auto-learn? ham=0.1, spam=12, body-points=0.2229, head-points=0.2229, learned-points=0
16:48:22 Sep 26 16:48:22.048 [19001] dbg: learn: auto-learn? no: inside auto-learn thresholds, not considered ham or spam
16:48:22 Insecure dependency in open while running with -T switch at /usr/lib64/perl5/IO/File.pm line 185.
-------------
Line 185 in File.pm is the "open" function.
System is SL 6.1 x86_64, perl is v5.10.1
I run MS as "postfix" and the perms for /var/spool/MailScanner/... are:
-----------
[root at mail rules]# ls -l /var/spool/MailScanner/
total 8
drwxr-xr-x. 5 postfix clamav 4096 Sep 26 16:48 incoming
drwxr-xr-x. 4 postfix apache 4096 Sep 26 14:13 quarantine
[root at mail rules]# ls -l /var/spool/MailScanner/quarantine/
total 8
drwxrwx---. 3 postfix apache 4096 Sep 26 14:13 20110926
drwxr-xr-x. 3 root root 4096 Sep 26 16:03 phishingupdate
[root at mail rules]# ls -l /var/spool/MailScanner/quarantine/20110926/
total 4
drwxrwx---. 2 postfix apache 4096 Sep 26 14:13 spam
-----------
The perms on todays quarantine directory look ok?
Could this be a failing perl module?
Does anyone have any pointers for me where to look next?
Thanks!
Vincent
