Can't exchange handle the virtual domains? I'd just add

company1.com smtp:bloddy.exchange.box
.company1.com smtp:bloddy.exchange.box
company2.com smtp:bloddy.exchange.box
.company2.com smtp:bloddy.exchange.box
company3.com smtp:bloddy.exchange.box
.company3.com smtp:bloddy.exchange.box

to the transport map on the Postfix box and be done with it.

Of course:

message_size_limit (default: 10240000 bytes)
       The maximal size of a Postfix queue file, including envelope
       information (sender, recipient, etc.).
