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'. >Date: Mon, 4 Mar 91 10:16:27 +0100 >From: MAILER-DAEMON@zam067 (Mail Delivery Subsystem) The domain name here is not fully qualified.

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. -- =*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= Neil W.
