I did this for years with my self hosted mail server until Vimeo refused to let me register. Basically, I didn't see any reason anyone needs to know that I'm running a mail server unless they already know my address. I wondered if it might help me avoid spam. No idea whether it actually did, but I just figured it wouldn't hurt to be a little more discreet.

It's not a huge deal, but I would have preferred to continue without one.
