As cfe+@andrew.cmu.edu (Craig F. Everhart) replies, the "bad file
number" message is rather misleading, but look at the other message,
"remote protocol error". It could be that the machine tries to talk
"sendmail-smtp", using only <LF> (or <NL> in UNIX terms) instead of
the RFC821-required <CR><LF> as line terminator. We've had this
problem when talking to DEC20/TOPS20 machines, e.g. SRI-NIC.ARPA.

Fix in sendmail.cf:

    Mether, P=[IPC], E=\r\n, F=mDFMuCX, S=11, R=21, A=IPC $h
