Hello all,
I have just had a weird email indicating that my server is spamming. This
resulted from my attempt to get setroubleshoot to send email
notifications.
I don't really understand how this happened, and I keep looking at the
headers wondering exactly what went on...
This is the message I received:

These are the headers for that email. As far as I can tell the email never
left my server.

And the actual mail was a standard setroubleshoot report detailing an AVC.
I admit I probably do not have this set up right, but I don't know what I
have done wrong.
In /var/lib/setroubleshoot/email_alert_recipients I have simply:
root(a)localhost.localdomain filter_type=after_first
Note that there is no ".org" after that.
I have not touched /etc/setroubleshoot/setroubleshoot.conf at all.
What do I have to do to fix this?
Thanks...

First thing I would do is check mail as root and try to send a mail message to
root(a)localhost.localdomain
