The MTA on your machine isn't properly configured.

Yes.  Your sendmail configuration is broken.

Fix your sendmail configuration.  *wry grin*  That line is pretty
obviously broken, but beyond that I don't have much advice; this both
isn't the place for sendmail questions (your problem is unrelated to INN)
and I personally haven't run sendmail in years.

If you have a smart relay machine on your network, you may be able to
change that line to point to the appropriate host, but given that $m is
apparently null, I think you probably have more serious sendmail
configuration problems than that and really need to overhaul your mail
configuration entirely.

You may be able to get help in one of the Linux or Unix Usenet groups.
