MailScanner ERROR

I setup a mail server followed the instruction here:
http://www.howtoforge.com/virtual-users-domains-postfix-mailscanner-mailwatch-centos5.1

So far everything seems fine. Lots spam mails has been catched. But in the maillog I see a lots errors:

Code:

Sep 24 15:19:06 zeta MailScanner[3229]: Clamd::ERROR:: UNKNOWN CLAMD RETURN ./razor-agent.log/Access denied. ERROR :: /var/spool/MailScanner/incoming/3229  

How do I fix this error? Do I need manual install razor? Where is the razor-agent.log?

Please help. Thanks.

 

There is another thing bothers me:

Code:

[root@zeta ~]# MailScanner --lint
......
MailScanner.conf says "Virus Scanners = clamd"
Found these virus scanners installed: clamd
===========================================================================
Filename Checks: Windows/DOS Executable (1 eicar.com)

Virus Scanning: Found 2 viruses

Is Razor installed? What's the output of

Code:

updatedb
locate razor-agent.log

?

 

Thank you falko for the reply.

Code:

[root@zeta /]# updatedb
[root@zeta /]# locate razor-agent.log
/var/spool/MailScanner/incoming/10086/razor-agent.log
/var/spool/MailScanner/incoming/10111/razor-agent.log
/var/spool/MailScanner/incoming/10717/razor-agent.log

I noticed:

Code:

[root@zeta /]# ps aux | grep MailScanner
postfix   4996  0.0  2.2  29984 23384 ?        Ss   Sep24   0:00 MailScanner: starting child

root     14911  0.0  0.0   4004   704 pts/0    S+   08:52   0:00 grep MailScanner

So I have 5 instances of MailScanner but I only have 3 corresponding razor-agent.log files. Could this be the problem?

 

some updates:

1. It seems this ERROR message happens randomly. Some time happens, sometime doesn't.

2. I checked the permission and ownership of the log file:

Code:

[root@zeta ~]# ll /var/spool/MailScanner/incoming/
total 84
drwxr-x--- 2 postfix clamav   4096 Sep 27 10:51 2374
drwxr-x--- 2 postfix clamav   4096 Sep 27 10:52 2545
drwxr-x--- 2 postfix clamav   4096 Sep 27 10:07 2631
drwxr-x--- 2 postfix clamav   4096 Sep 27 10:51 2633
drwxr-x--- 2 postfix clamav   4096 Sep 27 10:51 2635
drwxr-x--- 2 postfix postfix  4096 Sep 27 09:25 Locks

-rwxrwxr-x 1 postfix clamav  35840 Sep 27 10:52 SpamAssassin.cache.db
drwx------ 2 postfix clamav   4096 Sep 27 10:52 SpamAssassin-Temp

and

Code:

[root@zeta ~]# ll /var/spool/MailScanner/incoming/2545/
total 4
-rw------- 1 postfix postfix 796 Sep 27 10:52 razor-agent.log

3. I think Razor is a plugin of MailScanner. I did not install razor separately.

4. I really confused here: The error entry in maillog is from MailScanner. The ERROR seems from clamd (running as user clamav). And the razor-agent.log owned by user postfix. How this things(Postfix/MailScanner/Clamav/Spamassassin) working together? If it is a permission problem, why it doesn't happen all the time?

 

I manually installed razor and razor-sdk. configured following instruction at http://wiki.apache.org/spamassassin/RazorSiteWide

So far the error seems gone. I'll keep monitor it and hope this solve the problem.
