Tk Library Source Code

I've noticed a small bug in smtpd triggered by MS
Outlook. Sometimes, when you send a PDF file attached
to a message, Outlook sets the MIME type to
"quoted-printable" and the file is not base-64 encoded.

Since we read one line at a time, lines ending with
CR+LF will be converted by TCL in LF only; this causes
errors
with both Acroread and ghostview.

The patch splits the DATA section on LF only; CR is
considered a normal character; includes (and thus
obsoletes) the previously submitted patches for 
hostname in HELO, QUIT, etc...

The hostname display part of this patch has already been
applied to the source code in handling your previous patch.

The new part - changing the DATA handling - is not permitted
by the SMTP RFC given our current implementation. Section
2.3.7 explicitly states that lines end with CRLF (or "\r\n"
in Tcl terms). This includes the DATA section if no
extensions are enables.

The current implementation only supports the miminal SMTP
protocol.  In particular we do no implement the 8BITMIME
extension which is what I think you are really asking for here.

I stongly suspect that outlook is ignoring our non-support
and using 8 bit mime anyway.

I'm looking into this - we certainly should be able to
support this but I am not certain that this is the correct
way to do this.
