Hi Mailing-List,


I have set up a new MS installation and do not manage to get  filetype/filename
checks working inseid of rar-archives.



I am using MS with postfix and ClamAV as virus scanner. I have added the
SaneSecurity files for ClamAV also.


The filetype checks are working fine on 7z-archives and zip-archives are also
searched for unwanted filetypes. even Excel files are unpacked and checked. I
understand, that clamav is not able to check RAR-archives anymore, right?




This are the relevant setting ( I hope ;-)

 Maximum Archive Depth = 8

Find Archives By Content = yes

Unpack Microsoft Documents = no

Archives Are = zip rar

Archives: Deny Filenames =  \.com$ \.exe$ \.cpl$ \.pif$

Archives: Deny Filetypes = executable



This are my settings:


[root at mailscanner MailScanner]# cat /etc/redhat-release

CentOS release 6.6 (Final)

[root at mailscanner MailScanner]# rpm -q postfix



[root at mailscanner MailScanner]# MailScanner --lint

Checking version numbers...

Version number in MailScanner.conf (4.84.6) is correct.


Your envelope_sender_header in spam.assassin.prefs.conf is correct.

If any of your virus scanners (clamavmodule,f-prot-6,sophossavi,mcafee6,clamd)

are not listed there, you should check that they are installed correctly

and that MailScanner is finding them correctly via its virus.scanners.conf.
