That can't easily be done.  For anti-spam reasons, very few remote MTAs 
will accept mail from an MUA or MTA originating from an "unknown" IP 
address.  For an ISP MTA, this is one not within the assigned IP pool 
for its clients and for the big boys, it's anyone who isn't known as a 
valid ISP or who can't authenticate themselves via userid/password or TLS.

So, if you need the services of an external MTA, you will require 
configuration info that is specific to the client system.
