I receive a lot of email on the standard email aliases on my system.

Can I just delete the aliases in the section "General redirections ..." and the section "Standard RFC2142 aliases" preventing spam of is there a reason to keep these aliases?

Furthermore there is a alias called decode should I enable it? and is there a process that sends mail to this alias?

Are there any other tips and tricks apart from installing the spam filter as described in:

These are the aliases I reffer to that van be found in /etc/mail/aliases
Code:


These are the # Basic system aliases -- these MUST be present.
MAILER-DAEMON:      postmaster
postmaster:         root

# General redirections for pseudo accounts.
adm:                root
bin:                root
daemon:             root
exim:               root
lp:                 root
mail:               root
named:              root
nobody:             root
postfix:            root

# Well-known aliases -- these should be filled in!
root:                   myname
operator:               myname

# Standard RFC2142 aliases
abuse:              postmaster
ftp:                root
hostmaster:         root
news:               usenet
noc:                root
security:           root

The reason for keeping them would be to remain RFC compliant. That's your call. If you run a mailserver then it's only polite to keep postmaster open. You could drop webmaster if you don't run such a server, for example.

You can't be on the net in 2006 and not run some anti-UCE measures.

I've disabled these RFC2142 mail accounts and I havent noticed anything that goes wrong.

Only the amount of spam that can be delivered succesfully drops dramatically!
