The value of variable $myhostname is "server01", 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 nam e!

I add this to help you;

[root@web47 ~]# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=server01
GATEWAY=216.238.177.1

[root@web47 ~]# sysctl kernel.hostname
kernel.hostname = server01

[root@web47 ~]# hostname
server01

[root@web47 ~]# hostname -f
server01.mytruewebsite.co.uk


what shoud I do now?

[falko]

Try

$myhostname = "localhost";

in your amavisd.conf.
