Good morning Martin Hepworth
Restarted the service mailscanner and yet the policy described in / etc
/ mailscanner / files - not types.conf and applied as observed in test
with attachments and compressed files pure . Example executables files
when attached in the policy even deny the mailscanner does not block ,
already put debug in order to see something but does not return anything
, so that was checked informs entered the path of the program / usr /
bin / file now and then forwards it to the clamav anti -virus .
Example of policy
Contet of /etc/mailscanner/files-types.conf :
# To disable this feature , set this to just " Filetype Rules = " or
# The location of the file command to a blank string .
Filetype Rules = % etc -dir % / filetype.rules.conf
Content of / filetype.rules.conf :
allow text -
allow \ bscript -
allow archive -
allow postscript -
deny self -extract No self-extracting archives Self-extracting archives
deny executable No executables No programs allowed
# EXAMPLE : deny - x - dosexec In DOS executables No DOS programs allowed
deny ELF No executables No programs allowed
rename Registry Windows Registry entries ( renamed ) Windows Registry
files ( renamed )
I thank you for your attention .
