My point is, I made a minor mistake in configuring GMail. That was my own fault. Multiply that amount of configuration by a million, and see if you don't make a mistake. Do ongoing maintenance, and see if you don't make a mistake. Keep everything secure, make sure you're whitelisted by every major provider, and ensure no messages ever bounce one way or another.

My point is, fucking up is bad and easily costs you money. Giving yourself infinitely more ways to fuck up to save $50 a year is stupid. I don't know how I can put it more plainly than that. At this point you're pretty much just trolling.
