Yes. That is a *good* thing.

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. -- Nothing like grilling a kosher dog over human hair to bring out the subtle flavors.
