[AusNOG] Spam Filtering

[Ross Cheetham]

Before we moved our corporate email to Google Apps, we switched our spam
filtering from in-house to GFI Mail essentials "cloud" version.

Honestly it worked great, a few minor complaints with the user portal
(especially around reporting false positives or missed positives).

Can appreciate admins like to have "control" over things like spam
filtering, but IMO that is time wasted on other projects which could be
revenue generating, or adding value for your customers (even if that is
internal customers).

Pro's and Con's either way though. We are a smallish team so did not want
to spend time monitoring and caring for a proper spam filtering setup.

Cheers,
Ross
