I started playing with the sendmail stuff which came with
4.3 BSD and had a user point out a rude surprise.  He tried
sending something like this

    To: felix!zemon
    -------
    foo
    .
    bar

and received

    To: felix!zemon
    From: fritz!someone
    --------
    foo

The SMTP protocol seems to have ended the message at the
dot and ignored the rest.

I'm using the lanroot.mc and lanleaf.mc configuration files
in the no-named directory.  The message originated at a
leaf site and was sent to the root site (felix), where
"zemon" is aliased to "zemon@fritz".  Using the MH send
command with the verbose and watch options, you see that
sendmail sets up a SMTP connection and the receiver says
that the message text should be sent with the end indicated
by a line with a single period on it.  Well, the receiver
keeps his word and ignores the rest of the message.  This
is probably a bug given the following....

Now the strangeness.  Sending the same message from kelly,
another leaf site, to fritz using the address "zemon@fritz"
instead of "fritz!zemon" works correctly.  But sending it
from kelly using address "zemon@felix" also fails by the
time the message is finally delivered to fritz.

So what's going on?  Is this a bug in the protocol?  Has
this been solved?  Shouldn't these things be escaped like
"From" lines?  Or something?
