Nexenta - SMTP Server Settings

A common problem for users of NexentaStor, especially home users and people doing a trial evaluation of the software, is that, at least as of 3.1.3.5, it requires a real SMTP server somewhere else in order to send email. I'm often told no email was set up because no SMTP server or account was available (at home, this is often just permanently true, and in the enterprise this is often true during eval phases). This is bad - NexentaStor sends all sorts of alerts via email that it does not display anywhere else. Your appliance may be warning you of something, and you'll have no idea. There is a workaround, however, if the appliance can get to the internet and you have GMail (or can be bothered to set up an account)!
