           Summary: Reject the entire message if one syntactically faulty
                    recipient was found in the headers
           Product: Exim
           Version: N/A
          Platform: Other
               URL: http://bugs.debian.org/457096
        OS/Version: Linux
            Status: NEW
          Severity: bug
          Priority: low
         Component: Delivery in general
        AssignedTo: nigel@???
        ReportedBy: jidanni@???
                CC: exim-dev@???

I send an email CC'd to several people.

But one of those peoples' addresses I typed wrong.

Exim still sends the mail to everybody else.

And when everybody else replies, they also attempt to send to that bad
address, getting error messages.

I end up looking very bad.

Wouldn't it be nice if exim stopped my message in its tracks, instead
of just telling me "oh by the way, you just sent a mail that will make
you look very unprofessional if anybody tries to reply to address
XX@??? which is malformed but we let sail forth anyway in the headers
as a lesson."

Better would be "Sorry, you just attempted to send a mail with one or
more malformed address: XX@???. Rather than *even just* removing that
bad address and letting the mail sail forth, thus *still* making it
look like your forgot to include that certain somebody important in
your CC, etc., here is your whole mail bounced back to you for
reformatting so you can clean it up and try again (we dare not tamper
with it for you). We know that mail you send, from header to trailer,
reflects your professional image, and we here at Exim will do
everything we can to not knowingly let anything will errors sail
forth."

The above is for users sending from the local machine. Not for mail
coming in from "outdoors".

Me, jidanni, the bug reporter is not the kind of user to go meddling
with the exim configuration.

I just thought the above might be a neat exim default or "one click"
(one line) option choice... maybe something that one could pick on a
say debian configuration option... but no deeper... meddling with the
exim configuration scares me.

Please also see:

(in which probably we see the code is there, but just not switched on as
default... so probably "no bug")
