Problem with sendmail/bad file number?

[Ed Otto]

Mailing out from my machine works fine.  Incoming mail bounces as shown below.
I can use all other network features to and from my machine. Can someone please
tell me why this is happening?  Please note that this message is RETURNED mail;
the mailer daemon DID find the machine...
