  Sorry for not being clearer.

  With the example, ssmtp failed, i.e. it did not send a message.

  It should not have failed, but it failed because it used the (second)
From: line from the *body*, and that From: line was invalid ("From:
Frank Slootweg <this AT ddress DOT is DOT invalid>". It *should* have sent the
message to the From: line in the *header* ("From: Frank Slootweg
<franks_cygwin AT yahoo DOT com>").

  The failure message was:

> /usr/sbin/ssmtp: smtp server didn't accept RCPT To: command, replied
> "450 <this AT ddress DOT is DOT invalid>: Sender address rejected: Domain not
found".

(I don't know why the failure message says "RCPT To:" instead of
"From:".)

  Of course ssmtp should only use the From: line from the header, not
from the body. Suppose the body contained for example "From:
George DOT Bush AT whitehouse DOT gov". We would not want the message to be sent
with that From: line, do we? :-)

  I did some more testing and found that ssmtp does apparently *not* use
the To: line from the body. That would of course be even worse.

  I hope this explains the problem better.
