FQDN Misery Re: To: Postfix, Mutt And No Root Mail? & amavisd-new Install

[David Koski]

For an FQDN, find your hostname:

# hostname
myhost

Add this to your /etc/hosts

11.22.33.44	myhost.example.com	myhost

Now show FQDN:

# hostname -f
myhost.example.com

Of course 11.22.33.44 is your IP address.

You may need to add an alias for root in /etc/aliases (or /etc/postfix/aliases 
or wherever your file is) and run newaliases.  For example, add:

root: myname at localhost

or

root: myname

or

root: myname at example.com

or whatever.
