This work is to be done on the computer which is to be your mail server. You may sit at that computer's keyboard or work remotely.

These UNIX commands have been taken directly from a Terminal window - these are the commands I use - rather than having been composed after the fact. This is *exactly* what worked for me. I've taken pains to choose forms of the commands which should make sense to you even if you're new to UNIX.

Sendmail comes with your Mac OS X installation. The first thing to do is create a script to automate the re-initialization of sendmail when you configure it.

sendmail-update

The sendmail-update script is from http://www.macdevcenter.com/pub/a/mac/2002/09/10/sendmail.html.

#! /bin/sh if [ /etc/mail/config.mc -nt /etc/mail/sendmail.cf ] then echo Regenerating sendmail.cf m4 /usr/share/sendmail/conf/m4/cf.m4 /etc/mail/config.mc > /tmp/sendmail.cf mv /etc/mail/sendmail.cf /etc/mail/sendmail.cf.old mv /tmp/sendmail.cf /etc/mail/sendmail.cf /System/Library/StartupItems/Sendmail/Sendmail restart fi if [ /etc/mail/aliases -nt /etc/mail/aliases.db ] then echo Updating aliases newaliases fi if [ /etc/mail/access -nt /etc/mail/access.db ] then echo Updating access makemap hash /etc/mail/access < /etc/mail/access fi

I place this script (and my own creations) into ~/bin (which is on my search path). If you place it elsewhere you'll have to change my references to ~/bin/sendmail-update as appropriate.
