tar.gz archives

[Valentin Laskov]

Hi all,

today I received a letter with a file attached, named "01.2016.faktura 
187.xlsx.tar.gz". After unzipping it with

tar -xzvf 01.2016.faktura\ 187.xlsx.tar.gz

appeared application with name "01.2016.faktura 187.xlsx.exe"

How MailScanner treads tar.gz archives?

Regards!
