I've had a more encouraging reply:

"Yes, what you have noted is actually a known issue. However, the good news is that, its something we plan to address soon. We have a project in progress to restrict sending to be from verified addresses only.

Since this is likely to interfere with some users legitimate workflows it has to be introduced very carefully. So, no timeline at the moment, but we are working on it."


I replied saying that I thought that how useful this turns out to be (for example whether I could send mails 'from' an address I own, that's not an FM one) will depend on what they mean by "verified"...
