exim won't relay mail : FIXED

[dman <dsh8290@rit.edu>]

I have now fixed the problem where mail relayed by exim was dropped
somewhere because the (default) envelope-from address is not valid
outside of my own system.  (I broke the thread because I am sending
this from my Debian box via exim :-))

Messages may (read: will) be dropped if they don't have a valid
envelope-from address.  By default the envelope-from is user@host
where 'user' is the local user name and 'host' is this machine's name.
Since this machine isn't in any DNS tables the default envelope-from
address will be incorrect.  To fix this, edit /etc/email-addresses to
contain a line to rewrite the envelope-from to have the users "real"
email address.

I added
    dman: dsh8290@rit.edu
to /etc/email-addresses and now the envelope-from is valid (for me
anyways).  I would need to add a similar line for all other users on
my system, if they were to send emails.
