Amavis not working

Hello

I did a clean CWP installation today. But amavis did not work for me. What am I doing wrong?

I found the solution

amavisd -u amavis -c /etc/amavisd/amavisd.conf debug
 
The value of variable $myhostname is "Mydomain", but should have been  a fully qualified domain name; perhaps uname(3) did not provide such. You must explicitly assign a FQDN of this host to variable $myhostname in amavisd.conf, or fix what uname(3) provides as a host's network name!
