I had an old mac server, so I use Apple's gui. TBH, I don't even know if its sendmail or postfix under the hood. Never even got started using virtual domains.

I had an old mac server, so I use Apple's gui. TBH, I don't even know if its sendmail or postfix under the hood. Never even got started using virtual domains. I just run emails for one domain, so it never sounded like I should setup the virtual ones. I can't envision a situation where I would really need to do anything sophisticated with an email server, when I wouldn't just use google apps. I can do the basic "send and receive" email from my server, and I was able to let my gmail send through that (removing the "on behalf of" header). But other than that I'm probably a hosted email guy all the way. I've never spent any money on email stuff or been focused on it, so I don't have any feel for costs.
