You are using a proprietary MDA. You also mentioned this is across machines. Once you decide on this, you get what they give you, unless you hack it yourself. Sieve is filtering language. So what ever MDA you use, must support it to use it. If your MDA does not support specifying folders or manipulating files, nothing you do will change that. Dovecot + Sieve works because it is the same machine and simple file manipulation. You should take this up with your MDA host as it is not a Postfix issue.
