Actually, it does. I just tried setting my smtp server to port 25 & no security. I got this error message:
An error occurred while sending mail. The mail server responded: 5.7.0 Must issue a STARTTLS command first. i26-v6sm9327158ioj.33 - gsmtp. Please verify that your email address is correct in your account settings and try again.
So, it would appear STARTTLS is mandatory,

You and Per have noticed that gmail-smtp-in.l.google.com resolves to different addresses for each of you, I presume?
I had not, but that's not unusual. With the size of gmail, I would only expect it.
James used a different address again. So apparently google has inconsistent policies or has different policies at different locations.
submission vs. transfer,
Well perhaps for James, but you and Andrei used the same name and got different addresses. So that's not submission vs. transfer but perhaps location-dependent with different settings on the equivalent machines.
