1. INSTALLATION

Obtaining Sendmail:

Sendmail can be obtained from the primary ftp site:

• <URL:ftp://ftp.sendmail.org/pub/sendmail/>

Or the mirror on Sunsite UK:

• <URL:ftp://sunsite.doc.ic.ac.uk/packages/mail/sendmail/>

2. CONFIGURATION

Sample .mc configuration file for xciv.demon.co.uk.

In sendmail.cf, include at the end:

# Sources of junk mail 
F{JunkFull} /etc/sendmail.junk-full 
F{JunkDomain} /etc/sendmail.junk-domain

Scheck_mail 
# Bounce junk mail 
R<$={JunkFull}>                  $#error $@ 5.7.1 $: Local junk policy rejects
R$*                              $: $>3 $1
R$* < @ $={JunkDomain} . > $*    $#error $@ 5.7.1 $: Local junk policy rejects

Then populate /etc/sendmail.junk-full with complete email addresses you 
wish to reject, one per line:

spammer@aol.com
random-luser@compuserve.com

and /etc/sendmail.junk-domain with domains that you want to cut off:

enterprise.net
cyberpromo.com
