I am thinking of a session by session post-a-rama from Admin2005 (part 1)

SMTP Configuration Lab

Overview
I always enjoy this session after starting it up last year.  It repeats at least once each day (last year it ran twice due to volume on one day).  It is a reserved slot sessions since each person is offered a laptop.  Extras are offered "observer" only seats and can take a laptop if someone does not show.  Anyone that tries to get in without a reservation waits a few to see who does and doesn't show.  Luckily I do not think anyone got turned away from getting in at some time during the week.  Each session had every seat filled.

My Opinions
In this session I rarely look at the slides, and instead, take the attendees through step-by step testing and overview of functionality.  I make it a total free-for-all in questions and answers and force some audience participation.  I found that the majority are now utilizing some outside device or service for spam and virus filtering as a front end.  About one-third are using Domino as the front line.  This lets the majority secure Domino even further by restricting who can connect directly.

Not using Domino as the front end comes as no surprise, even with Blacklisting and relay enforcements.  The people are having issues with spam, that goes far above the call of Blacklists.  I introduced Whitelists from Domino 7 in each session and combining that with the front end services and devices, they can totally lock down Domino as long as the filters catch it.

I am thinking that Domino will be adding some advanced spam abilities soon to keep up with demand.  Maybe relying on some filter technology like Ted Stanton posted here.
