I think I see what you're problem is. It's not the sender header, as
sendmail shouldn't be adding that in your case. It's the actual smtp
exchange. You're running into more restrictive spam checks. Primarily
ones that require the MAIL FROM domain to be valid, but you'll also
encounter ones that require the sending host to identify with a valid
hostname in HELO.

I'd change your server's configs so it identified as something
externally resolvable. using -f may solve the MAIL FROM error, but it
won't solve the HELO problem. (though you may not have encountered that
yet)

don't rename the machine, just have sendmail use something like that.
