Dear Maintainer,

Tried to installed 'exim4-base' after its most recent update and failed.

Implemented a rough draft of CIS Security Debian 11.

The portion about /tmp mount partition having that 'noexec' mount

Well, we will not be able to install exim4-base package anymore 
if this hardening effort continues.

Besides, who is still trying execute a script in /tmp directory.

Correct action is to do 'bash /tmp/your-script' or 'perl

Not to execute directly from '/tmp/your-script'.

Best action is not to execute that script directly in /tmp.
