Subject: block a particular double extension files in amavisd.conf

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?
