The following alert appeared on the Oz-ISP mailing list.

It appears that Linuxconf over-writes the Sendmail-8.9 conf
files
with Sendmail 8.8.x config.  It appears that Sendmail-8.8
still has
some serious bugs in prevent spam as indicated in the
following mail
message extract.

Is anyone looking at this problem ?
------------------------------------------------------------
---------------

For those people still using sendmail 8.8.x in hostile
environments,
note that your anti-relaying is very likely to be
compromised. ORBS
and
RRS are listing 8.8.x as open relays (as they are relaying)
because
of this.

Here's an example of poor.victim.com.au relaying spam to
tom@oz.tm:

220 poor.victim.com.au ESMTP Sendmail 8.8.5/8.8.5; Wed, 25
Aug 1999
09:55:39 +1000 (EST)
mail from: <lkjfe@netscape.net>
250 <lkjfe@netscape.net>... Sender ok
rcpt to: <"tom@oz.tm"@victim.com.au>
250 <"tom@oz.tm"@victim.com.au>... Recipient ok
data
[... insert porn spam here ..]

Given the popularity of RedHat 6 and Linuxconf with ISPs
who are a
little short on Unix, inparticular Sendmail skills.  This
could be a
major problem.
