[Lincoln LUG] Email Filtering

[Kevin Hall]

Hi Folks

I hope you are all well.

At a secondary school somewhere in the UK, a teacher accidentally sent 
an email to all the students. Students, being students, did Reply All 
back. Some students chose to reply back with pornographic images and 
have been reported to the police for distributing pornographic material 
to minors.

I work in a primary school so have no experience of this as staff do not 
email students and when we teach email, I have a linux box that just 
sends emails internally on our network.

So my first thought was, surely there must be software out there that 
will scan emails for this sort of thing as I assume every business would 
check for this by default. Is this the case?

Regards

Kevin
