Our exchange server has been getting spam/junk mail that contains only one or two sentences of garbled information...like a line or two from a strange play, novel, press release.
We've received three in the last 24 hours, all from different domains and they have no attachments, advertisements, or links.
Here is an example...
"The Volcano closed for a second and more elaborate renovation in February 2008 and reopened on December 8, 2008. This led him to new ideas. Black Music Research Journal 8."
What exactly are these and how do you filter them when they have no malicious content and keep coming from different domains each time to get around the blacklisting I do?
Thanks for the help,
