I had the same problems too. Many MTA reverse lookup the envelope
sender and reject mails with an unresolvable name.

You could use envelope header rewriting to replace the envelope sender
by your email address. With sendmail you would have to use the
masquerade_envelope feature together with a genericstable.
Look at the sendmail docs or http://www.sendmail.org for details.

BTW: Fortunately, I do have a valid hostname right now. Made my
sendmail config much easier to read.
