[Exim] Amavis - Exim - HELP

Hello,

I try to install Amavis with Virus Scan for Linux v4.14.0 and Exim 3.22.

Everything seems to be ok when I compiling, but when I try to make it works....

It doesn't work and tell me this :

2001-10-24 16:06:15 15wOff-0007kz-00 == milhau@??? T=amavis defer (0): Child process of amavis transport returned 75 (could mean temporary error) from command: /usr/sbin/amavis

Does someone can gice me an idea, where to search?

Thank you.
