Re: Need help installing postfix on my home server

Postfix -- at least recent packaged versions of postfix -- is a pretty much
install-and-go type of software.  Here's a quick step-by-step guide that
should be enough to get you started:

1) Install the postfix package.
2) Find your 'main.cf' file; usually /etc/postfix/main.cf.
3) Edit 'main.cf', and set the following variables appropriately:
   - myhostname
   - mydomain
   - myorigin
   - mydestination
      - likely $myhostname, localhost, localhost.$mydomain
   - mynetworks_style (as you're just sending, set to 'host')
   - inet_interfaces (as you're just sending, set to 'localhost')
4) Run 'newaliases'.
4) Start postfix, and set it to start by default.

Note that you may also want to set the 'relayhost' variable in main.cf, to
be your ISPs mail servers.  I would only suggest doing this if required,
though.

Voila, you now have a fully functional postfix setup.  To test it,
try running:

  # mail -s "Testing outbound mail" [email protected] < /dev/null

You should, shortly, get a message in your inbox.  If not, look in your
mail logs for reasons why.
