We get 'waves' of spam which are addressed to both long-time employees (usually executives) as well as long-gone employees. It's safe to say that ANYTHING sent to those ex-employees is spam but how do I use those messages as an instant filter for the valid addressees?
I assume I need to learn how to use the Bayesian filter but I've been avoiding that because of the apparent effort required to maintain it. Also I'm concerned that there won't be a quick enough turnaround on filtering, e.g. if 10 copies of a new spam arrive and the first several instances are addressed to current employees, they will 'pass' the filter before the known-bad addressees get scanned and added to the filter. I should also point-out that our SA setup is acting as relay to an internal server so once messages are passed they are no longer accessible to SA, i.e., we're running Postfix but only as a relay not as the primary mail store.
