[SA-exim] "Unknown Failure"

[Robert Wickberg]

I have exim4 installed on my up to date debian testing box. Now I installed
SA and SA-exim, and changed pretty much nothing except commenting out that
one line in sa-exim.conf necessary to get sa-exim to start working. Now my
incoming mail headers contain the following:

X-SA-Exim-Connect-IP: 209.198.87.109 X-SA-Exim-Mail-From:
***@sover.net
and

X-SA-Exim-Version: 4.2 (built Thu, 03 Mar 2005 10:44:12 +0100)
X-SA-Exim-Scanned: No (on
localhost.localdomain); Unknown failure

Can anyone tell me what's happening, or at least give me a method to
troubleshoot?

I take it from trying to do a google search on SA-exim and "Unknown Failure"
that this isn't an uncommon problem, as what I got back was a lot of mail in
mail archives that has this in the header, and nothing much helpful.

Thanks
