The Perfect Server - CentOS 6.2 x86_64 With Apache2 [ISPConfig 3] - AMAVISD

[epretorious]

There appears to be a detail missing in Step 14 ("Install Amavisd-new, SpamAssassin And ClamAV") of "The Perfect Server - CentOS 6.2 x86_64 With Apache2 [ISPConfig 3]":

1. When performing Step 14, the Amavisd init.d script (/etc/init.d/amavisd) complained...

[eric@ispconfig-1 ~]$ sudo /etc/init.d/amavisd start
Starting amavisd:   The value of variable $myhostname is "ispconfig-1", 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!
                                                           [FAILED]

2. This prevented mail delivery and lead to lots of these errors (in /var/log/maillog)...

Editing /etc/amavisd/amavisd.conf (i.e., Setting $myhostname to the FQHN of the MX) resolves this:

[eric@ispconfig-1 ~]$ hostname  -f
ispconfig-1.example.com

[eric@ispconfig-1 ~]$ grep \$myhostname /etc/amavisd/amavisd.conf
$myhostname = 'ispconfig-1.example.com';  # must be a fully-qualified domain name!
