+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.
