Blat - Windows Command Line SMTP Mailer

Users generally do not know anything about the headers, or
care. To them, they want to know if the message looks right
in their mail reader.

If you provide a file that is plain text, and a file that is
html, let Blat do the work for you. I added code to support
this, and have tested it, Blat is adding the correct headers
to make this work properly. I experimented using plain text
from a Microsoft MSN Groups message, and the html from that
same message. After making sure the message source looked
right, I sent the message to a few other people for their
opinion on its appearance.

I understood your idea, but who is setting the Content-Type
in the Header? How will be the boundary?
I think to give more flexibility to users (they know how the
Header should be) the option

-noct = No default Content-Type

is a good solution, because using -penguin the header in my
tests is ok except that I have 2 Content-Type defined.

blat mail.txt -to test@test.com -f user@test.com -
subject "Test" -penguin

Mail.txt:
Content-Type: multipart/related;
type=multipart/alternative;
boundary=----test.com
...

Header of send email:
...
Content-Type: text/plain; charset=ISO-8859-1
Content-Type: multipart/related;
type=multipart/alternative;
boundary=----test.com

If you need some support for testing, do not hesitate to
contact me directly

The option is not -penguine, it is -penguin.

If I create "-althtml <filename>" option for you, then you
do not need to have custom Content-type headers. The
-althtml option would let you give a filename that has plain
text for your normal html file/message body.

blat <htmlfile> -to <...> -subject <...> -althtml
<textfile>

Blat would take the <textfile> as the first part in the
multipart/alternative, then use <htmlfile> as the second part.

-penguine?
Blat v2.1.0 does not understand this argument. No entry in
syntax.txt.

Actually I do not need the text/enriched part, this was only
an example from RFC 2046 document. My gol is not to put a
text like " if you read this your email-program does not
support html ..." but to include the hole mail text in plain
format. So that people supports html-enhanced, see the html
mail, and the others the plain text. Please refer to RFC 2046
5.1.4. This could be done with Content-
Type=multipart/alternative. In my case, the html message
includes embedded images and this require the Content-Type
requested. The body will include plain text,html text and the
images. Please look at my attachement. (I'm sending always
email in particular format, but the client which generates the
email and the smtp server are very slow)

I tried to send using argument -a1 which adds the Content-
Type, but blat adds automatically the Content-
Type=text/html (=-html)
(command: blat mail.txt -to test@test.com -f
boris@test.com -subject "HTML/PLAIN Text" -a1 "Content-
Type: multipart/related;type=multipart/alternative;boundary=-
---ekeryx.com")

So the best think will be to have an argument which does not
add a default Content-Type if -html/-embed/-enriched is
omitted or to have an argument like -ct "Content-Type=..."
so to defined a custom Content-Type

First, to get more than two custom headers, use the -penguin
option and have your headers in the first lines of the message.

Next, if we created a new option -althtml to put that text
into the message, would this work for you to set the
multipart/alternative? The text/enriched message would not
be automatically included by Blat. Blat would add a plain
text warning message like "We attempted to deliver this
message to you with HTML formatting. However, your e-mail
program does not support HTML-enhanced messages."

In order to have text/enriched from html, Blat would have to
learn html/xml to make the conversions. Otherwise, Blat
could strip the html/xml tags and leave just the text. It
could also convert <BR> to carriage return/line feeds.

As another choice, the -althtml could be used with a
filename that would be the text you want. Or it could be
two filenames, the first file would be the plain text
message, the second file would be the enriched text message.
