why not just point them at a hosting service like google apps, and let google keep things up to date?
Costs money,
Yes. That is a *good* thing. Running an unmaintained mail server is a BAD thing.
and also the problem is that gmail imposes heavy spam filters and "reputation blocks" meaning smaller providers with low email volumes,
I think you are confusing gmail and google apps (or whatever it is called now, seems to change all the time).
Another thing is that you cannot impose IP restrictions when using Google Apps, or have SSO with trusted access from inside the office. (for example - scan your badge at the office door, your personal computer is automatically logged on and you get access to everything).
Wow. That sounds sooooooper not secure.
With locally hosted servers, of course you have to keep them updated. Most linux distributions can keep them updated automatically.
You cannot keep a mail server automatically updated, sorry. That is a fantasy.
You can either spend money on someone know knows what they are doing in-house (more secure, more control, more money), or you can spend money on outsourcing someone who knows what they are doing (less money). The other option involves a pair of smoking boots and a crater and I do not recommend it.
