If I (mis)configure it to use the full machine name instead of just the domain 
name, (as I've found to be the default in programs like pine and mutt) the mail 
bounces. 

rumblefish doesn't resolve externally by design, and the user should be 
configuring email to resolve to @tripwire.com, not @rumblefish.tripwire.com. 

The senders email address is usually added by the program the mail is written 
with.
