[TriLUG] Open source spam control & filtering?

[Chad Thomsen]

You make some excellent point David.  The more I think about it I might go
with a comercial solution.  I am afraid of adding anything else complicated
to the mix here as I am the only network guy here and if I leave I think my
shoes would be hard to fill as I run so many different things between Cisco,
Motorola, AS400, Citrix, Linux (snort)  Windows yadda yadda.  Why add the to
the complexity.  " someone else is responsible/accountable if the product
fails to deliver!!" is the major kicker here for me.  8-)

I am mainly looking at Symantic Brightmail, Iron Port, Barracuda,
Cypertrust, Trend Micro (since we have there desktop AV solution).

Thanks!

Chad
