I am getting an odd response from a mail server that I am attempting to send
a message to (fast.net).  Here is the message that their server is sending
at the end of my message.  "451 See http://pobox.com/~djb/docs/smtplf.html";
A main snippet, referencing the error, from that website says:

"It was generated by qmail, an Internet message transfer agent. Your mailer
tried to send an e-mail message to a server running qmail. Unfortunately,
qmail spotted a problem: your mailer sent a bare LF."

There are a couple of things that are odd about the situation.

1. The mail that is being rejected appears to have a CR at the end of the
message.  The message end just like all the other messages that are sent or
received by our server.  Here is a portion of the capture of the data stream
from the message that generates the error.

.
451 See http://pobox.com/~djb/docs/smtplf.html.
QUIT
221 Catch you later

In the actual capture utility window it shows a box [] after the period just
above the line starting with '451 See...'

2. The mail that is sent and rejected is auto generated by one of our web
servers (tankstatus.com) based on an event.  It is in HTML format and
relayed through our Exchange 5.5 server (on separate box).  An original
message is attached.

3. I am able to sent mail to the host in question (fast.net) from my work
station (outlook 2002).  The main difference is that my mails are not in
html format.

4. We operate this service for several customers and have never had a
problem with them receiving our automated emails, which for the most part
are identical.

This is so odd that I am not even sure where to go to trouble shoot, or even
what question(s) to ask in this list.  Has anyone got any insight, former
experience, suggestions or smart ass comments?  At this point anything would
be helpful.

Doug
