Is it right to blame Google/Yahoo for deprecating an email forwarding service?
3 by alumnisfu | 1 comments on Hacker News.
My former university, Simon Fraser University, had a service for graduates where you could keep your old xxxxx@sfu.ca email address after graduation they would forward messages to an external email address. I've been using this email address for 20 years now but they suddenly announced that they have to deprecate this service "to comply with industry-wide regulations" led by Google and Yahoo. A FAQ was just posted (https://ift.tt/VBZ1CUD) but it has very little information as to why this was necessary. Is there a legitimate technical reason why the Google/Yahoo changes would make it impossible or difficult to continue offering mail forwarding?
