Problems with "Sender:"-header in 'rtin'

I'm trying to post to some newsgroups using 'tin' (or to be
precise 'rtin'). I'm using a remote-server I got access to,
but have run into a little problem...

In the options-menue (M), I've specified my mail-address
and name, and this shows up in the "From:"-header when
I post.

Unfortunately, when I'm done editing and try to post,
a "Sender:"-header is generated. This appaer to be
combining my username, hostname and domain-name on
my *local* machine. Unfortunately, tin then rejects my
article because this "Sender:"-header is invalid -- no surprise
as I don't *really* have a domain-name (as my computer
isn't permanently connected) and use a generic domain-name.

What I'd *like* to do, is either replace this generated
"Sender:"-header with my email-address (same as "From:"),
or maybe a combination of my username on the remote
nntp-server and the remote servers name (the servers name
is specified in the NNTPSERVER-eviroment-variable).

I really thought 'tin' did this itself when invoked as 'rtin'
towards a remote-server... after all, the settings on the *local*
machine should be obviously moot.

Any suggestions? Either by enviromental-variables, etc-files,
tin-configuration or options to tin?
