Re: [PLUG] Backup MX Question

[Andrew Libby <andrew.libby@gmail.com>]

I've heard that spammers will default to the lowest priority MX in the
belief that
the anti-spam measures used at this level are not as thorough as those
at the higher
(highest) priority MX. 

If I recall correctly, one approach was to have a third MX that
basically trashes everything
as a spam subversion measure.  There may be more to the configuration
than that, but I don't
recall.

Anyone heard of this, know more about this?

Thanks.

Andy
