We just put in server, nice little super micro system, 5 disk array, SATA with about 6000 e-mails. I think it was around 4 k for everything, and it can do quite a bit more, not loaded up much at all.

At $0.35 each that is almost $2,600/month or $31,200/year. That is a large expense for email. That's large enough, that it's almost certainly more cost-effective to do it in-house. If I were inclined to make up bogus rules-of-thumb, I'd probably say that if you have fewer than 1000 mailboxes it's likely less expensive to outsource, and over 5000 you should be doing it in-house. There's a lot of grey area between those two number, though. If you do it in-house, there are hardware costs, software costs (even with open-source you should be donating to the projects that keep your business running), electricity, cooling, paying someone to keep an eye on all of the above and to fix it when it breaks... Many people overlook all these overhead expenses. When you outsource, they give you one number. In-house, you have to remember to add up all those little numbers, and not everyone does.
