Yes, it does.

This means that IMail should try 212.242.40.84, and if that fails, it
should try *one* of the other three 212.242.40.x's.

That's a bad conclusion.
The IMail SMTP logs will show you exactly what happened. For example, it
is quite likely that the backup mailserver responded with a temporary
error. Or perhaps the backup mailserver was down, too, or unreachable.
