Don't know if this is related, but we recently discovered (while
hunting for a problem with some self-written Winlose 95 rsh-client)
that Winlose 95 doesn't know how to handle TCP connections. Not that
this really suprised me, but it effectively makes any rsh command
useless that tries to take data from stdin.

The bug is that Winlose never sends a FIN flag, but immediately sends
a package with an RST in it. This causes the remote command to be
aborted (as opposed to see a closed connection, and process it as an
EOF condition).

Since your problems always happen while the sendmail is waiting for
the QUIT handshake, it may be the same problem.

Dunno if this is only apparent for some version of Winlose 95.
