[svlug] mail relaying, jitterbug and me

[josh]

Hi all.

I've recently tried to set up Jitterbug
(http://samba.anu.edu.au/jitterbug/) as an issue tracker for my
current project.  I'd used it before and heartily reccommend it.

The problem is that it relies on email to work, and my default install
of slackware8 doesn't seem to want to play nice.

Here's my configuration:

joshwalker.org points at my ip.  I have a stupid dsl 'router' that
points ports 25 and 110 at my linux machine.  When I try to email
anyone at joshwalker.org, I get this error message back from my work mail
daemon:

<code>
  Recipient address: me at joshwalker.org
  Reason: Remote SMTP server has rejected address
  Diagnostic code: smtp;550 5.7.1 <me at joshwalker.org>... Relaying denied
  Remote system: dns;mail.joshwalker.org
(TCP|128.125.253.6|59493|[my ip]|25)
(dslxxx-xxx-xxx.sfo2.dsl.speakeasy.net ESMTP Sendmail 8.11.4/8.11.4; Tue, 6 Au
2002 10:11:14 -0700)
</code>

I wasn't really planning on learning sendmail when I started to set
this up.  Can anyone give me a quick pointer or two on how to allow
people to send me mail at my linux machine?
