Starting amavisd: The value of variable $myhostname is “ip-10-102-202-207”, 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!
Just edit the \etc\amavisd\amavisd.conf
Take the comment out of the $hostname line and enter the fqdn in the value.
