There's no doubt that e-mail is a vital component in business today, and as such we pay particular attention to our e-mail infrastructure.

We use dedicated systems as Mail Transfer Agents, of course, and run Exim on those, with as little ballast as possible. What we do though, is to give each MTA its own DNS caching server, and generally try to ensure all services the MTA requires are close to it, network wise.

These servers are closely monitored with Nagios. I've written bits and pieces of how we use Nagios in monitoring, but I want to bring those together:

Giving your monitoring environment a bit of thought (and quite a bit of work) quickly pays off. It is a relief to be able to look at your monitoring panel (or Web page) and see something like this: No red. No Yellow. All green. The best there is! ;-)
