While I agree that installing Dovecot, and perhaps Postfix, and some other tools can be rather trivial, I switched to Google Apps when I was world-travelling with my family and my VPS provider back in 2008 basically disintegrated off the face of the earth.

Google Apps to the rescue. I created a Google Apps account, update my MX records and mail was restored in about 15 minutes (plus any DNS propogation time). This made Google Apps a huge win for me. It was supposed to be temporary, but am still using to this day.

But, I still have a Linux box or 2 that could handle email within 5 minutes if needed.
