steve@unidata.ucar.edu (Steve Emmerson) (03/05/91)

Would someone please tell me why the following message bounced?  It used
to go through just fine.

Thanks,

 I short, because the 'sendmail' on zam067.zam.kfa-juelich.de is poorly
designed and misconfigured.

 This 'Received:' line indicates a design problem in the 'sendmail' binary.
It is saying that the message from 'MAILER-DAEMON@zam067' actually originated
on 'unidata.ucar.edu' which is incorrect.  To be more specific, the mail
bouncing code is failing to undefine '$s'.

  The domain name here is not fully qualified.  This is a mis-configuration.

 Another case of a host name not being fully qualified.

><<< 553 Local configuration error, hostname not recognized as local
>554 <zdv145@zam067.zam.kfa-juelich.de>... Service unavailable: Bad file number

 Because of configuration errors, the system does not recognize an address of
the form 'user@zam067.zam.kfa-juelich.de' as local.  It turns out (discovered
by remote probing) that it recognizes 'user@zam067' as a local address, but
does not recognize 'user@zam067.zam.kfa-juelich.de' as local.

 Short of reconfiguring your own 'sendmail' to work around these problems,
there is not much you can do to get a message through.
