Once again, using 3rd party services bites a company in the ass. What they should have done is hosted the old domain's email on a cheap VM - perhaps the free tier Amazon offers to new accounts - and simply auto-forwarded from that.<p>On the second one, never ever change more than one thing at a time - don't change your domain <i>and</i> move to https. Just do one thing at a time.<p>Both of these are common sense for old school system admins like myself, but it seems like the new DevOps types would rather re-learn all the hard lessons from scratch.
