block a particular double extension files in amavisd.conf

[Indunil Jayasooriya]

Hi,

I want to block files having double extensions. while users surf internet,
some files such as* e7ea.tmp.exe* will be automatically downloaded.


e7ea.tmp.exe is a ransomware. Attackers can send mails with files of these
types as well.

Now, I want to block files having double extension such as filenames
*.tmp.exe* format.


I think below regex is OK to insert in to amavisd.conf file.


*qr'.\.(tmp)\.exe$'i,  * # block this double extension


any comment?

cat /etc/motd
