> Sure, but how long would your new server keep working (i.e., delivering mail to GMail, etc)?

I can't see the future, if the big email providers who likely have some of their trolls posting in the comments ever decide to start choking out us personal email server runners, then it'd be game over. If things remain for the next 20 years assuming I live that long then deliverability would be 100% for the next 20 years.

I don't spam, that and don't make a finger fumble edit like I did the one time in over 20 years and didn't check to make sure it was working correctly first.

Also, I use http://www.mxtoolbox.com/ to keep an eye on my server.
