I&#x27;m in the same boat as you - running a personal&#x2F;friends&#x2F;family mail toaster for 16 years now. But I disagree that Google have made the administration harder.  Internet mail servers don&#x27;t live in isolation, and context has always been changing.  I have no issue with adapting configuration as expectations change, so Gmail&#x27;s evolution has never inhibited my ability to exchange email with the world.  This move is no different.  Really, I feel that the elephant has been tremendously careful <i>not</i> to tread on the mice.<p>I don&#x27;t believe this particular change materially improves security, since it isn&#x27;t representing an end-to-end behaviour, but if it raises awareness and challenges mass surveillance then so much the better.<p>Personally I would like them to advocate for other necessary infrastructure advances and include, for non-IPv6-capable MTAs, an icon of a lurching monster that refuses to die.
