Postfix - Forwarding deferred emails to another postfix server

Hello Guys,

Question
I have a postfix server which is running on Ubuntu,Somehow my server is blacklisted with some xxx.com due this the xxx.xom is not allowing incoming emails from my server. so can I forward the emails which are in queue (postfix) to another postfix server to send those deffered emails ?

Can someone help me how can I achieve this ?
