In the past there was an option to assign your own domain to the MS outlook mail service (for free). I did that and use outlook.live.com ever since as my mail provider using my own domain.I hoped that using outlook as mail provider will boost the credibility of my emails so that they are not constantly marked as spam just because the domain is not widely used. This has not come true but I still have a free mail service behind my domain :)What perks do you have that are not available any more but still work?
