You can specify a particular file type (“exe” files for example) or common groups 
of attachments in the 

attachment-filetype

 and 

drop-attachments-by-filetype rules

. AsyncOS divides the attachments into 

the groups listed in 

doc

mdb

mpp

ole

pdf

ppt

pub

rtf

wps

x-wmf

xls

exe 

java 

msi 

pif 

Filtering the Executable group will also 
scan 

.dll

 and 

.scr

 files, but you cannot 

filter these file types individually.
