OT: Postfix Masquerading

[Lance Haig]

Hi,

Apologies for the off topic here.

Can someone give me a (l)user explanation or point me in the right 
direction to setup outgoing *Masquerading
*
I have a smtp relay that is relaying our system notifications from 
multiple internal hosts.
these hosts attach the internal domain ot all their e-mail and this 
natrually does not have any dns records in the public domain.

How would I setup postfix to "formfill" the domains with a valid 
external domain?

Thanks

Lance
