Having a second postfix instance between amavisd and the email server is going to make things way more complicated. Amavisd is perfectly capable of speaking smtp/lmtp by itself, so unless you need to perform complex mail routing you could directly send the filtered mail to the windows server. Other than that, I have very similar setup (fetchmail->postfix->amavis->cyrus-imap, where all hops but the first are done with lmtp) that has been working quite well for the past few years.
