Agreed to all of that, and you also want to disable "non-remote" images, 
because exploits to the libraries that implement those are endless, and 
it's super-targetable remotely (you just type in the target's direct 
email address, or send to an unsanitized list they're on, from anywhere 
in the world, and chuckle to yourself). HTML and DOM processing 
implementations are not known to be as buggy as the 2D pixel map libraries.


(In the email client/MUA I've been wanting to write for years, and to 
which I alluded recently, when listing off some Racket project ideas... 
I'd actually also do an HTML-to-plain conversion from scratch, for 
security and other reasons.  A conversion is necessary because you can't 
just show the plain text of the MIME alternative content type, because 
it's often different/empty/missing, and the HTML represents the de facto 
canonical contents of the email.  In the meantime, Sylpheed and Claws 
have some security merits, but I'd try somewhat different approaches.)

Right.  The main point, for me, is the uncertainty that I'm seeing everything I 
should see.  in a properly configured (in my opinion) email client, a lot of 
HTML features will be disabled for security reasons, including such things as 
cookies, javascript and remote images...

My point wasn't that a lot of messages came in at once, it was that they
were all related to one topic (sending email from within Racket) but they
all had different subject lines.  Google Groups (where the list is
archived) threads conversations based on their subject line, as do Gmail,
Apple Mail, and probably most other mail clients.  Hitting 'Reply All' on
an earlier message (your own or someone else's) is less effort than
composing a fresh email, it will be less obtrusive in people's inboxes, and
(most importantly) the list archive will recognize that all the messages
are connected and thus it will be easier for future readers to follow the
conversation.

['John Clements' via Racket Users]

I see a number of very minor issues in your code: 

1) It looks like you have wrapped the keyword arguments in square brackets. 
These aren’t necessary. They’re used in the documentation to indicate optional 
elements.

2) It’s worth noting that these arguments are optional, so you can leave out, 
e.g. #:port-no (since you have it set to the default), and the final 25.

3) You seem to be missing arguments to the optional #:tcp-connect and 
#:tls-encode arguments; these are used to provide alternate connection and 
encoding functions, if you like.

4) The server address shouldn’t have a login. Something like “server.de”.

5) the from and to addresses and authenticated user, on the flip side, 
shouldn’t have a host. Something like “sender” and (list “receiver”)

Putting these all together, I think you’re looking for something like this:

(smtp-send-message  "server.de"
"sender"
(list "receiver")
"NEW MESSAGE SMTP !"
"HI , THIS IS THE MESSAGE !"
#:auth-user  "sender" 
#:auth-passwd  "123456”)

… but it’s not entirely clear.

It looks like the first issue, with the brackets, is the one that was stopping 
you, by giving you an error message that blocked you.

These messages were caught in a spam trap. I just approved all of them
at once. This isn't the OP's fault. (And is the html thing really that
big a deal?)

Hi MHE,

Quick requests:

#1:  Could you please not send HTML-formatted emails?  They're ugly and
distracting.  Keep it to plain text unless it's essential.

#2: Please stop spamming the list with slightly divergent items on a given
subject.  Keep it confined to one subject line so that Gmail and the Google
Group will thread the discussion properly.  That way everyone can benefit
from it in the future and it doesn't choke our inboxes as much.

Thanks!

Dave
