Not sure this is helpful, but for years I've hidden my actual host I send 
mail from which is 

unix.hobbeshollow.com

by putting the following entries in my mts.conf

localname: hobbeshollow.com
masquerade: draft_from mmailid username_extension

This allows me to send email as [email protected].
hobbeshollow.com is my domain.
I pay a 3rd party to connect for my outbound mail from hobbeshollow.com
a nominal fee annually because ATT turned off that capability about 18
months ago.
