I'm sorry, but I can't find the 4.1.4 sources there.  That seems to just
contain sources for a different program called "nail".  Somebody else
suggested I try to use it, but every version I tried to compile wouldn't even
build on my machine, so I couldn't even start to look and see if it would
work for me.

I'm perfectly willing to modify my mailer to add "In-Reply-To" (I accidentally
said "References" in my last message), but I need the sources to start with.
Does that site have them?
