Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hello All, Does anyone have a script which scans a netblock for an open mail relay and returns the FQDN of that server? I have just had another SPAMMER reveal that one of my smtp hosts was hijackable...they sent mail all night long!!! I would like to be able to periodically check this and report it to the main mail account. Please let me know.
