As example mail from root@sx1.labs.polarion.com should be masqueraded to mail from root@polarion.com and etc. This is very easy fix in sendmail, but how to do this in postfix - and not to break virtual domains configuration.
I believe in your /etc/postfix/main.cf file, just add the following:
masquerade_domains = foo.example.com example.com
Postfix docs: http://www.postfix.org/ADDRESS_REWRITING_README.html#masquerade
