|The MHTML standard allows:
||But use today only:
||How to do this:
|Existing web pages to be sent unchanged via e-mail, using the new Content-Location
||Use Content-ID for links between HTML text and in-line images, all mailers do not
yet (April 1998) support Content-Location.
||Most mailers today (April 1998) produce Content-ID links to images if you use the
text editor of the mailer to produce your messages.
|Images can either be sent as parts of the message, or referenced from their web locations.
||Include images as part of the message, do not reference their web addresses.
||Edit the message with the editor built into the mailer. In Outlook Express and Netspace
4: Paste the image into the text you are writing. In Eudora 4: Save the image in
a GIF file. Drag the file icon into the text you are writing. Do not paste
the image into an Eudora 4 message, Eudora will put the image in a format which many
other mailers cannot read.
|All kinds of HTML features can be sent in e-mail.
||Avoid advanced HTML features unless they are essential for your message.
||Do not use any other HTML tags than the following:
<b>, <i>, <underline>, <nofill>, <param>, <html>,
<pre>, <smaller>, <bigger>, <center>, <flushleft>,
<flushright>, <fontfamily>, <color>, <paraindent>, <h1>,
<h2>, <h3>, <h4>, <h5>, <h6>, <em>, <strong>,
<cite>, <address>, <title>, <head>, <body>, <blockquote>,
<code>, <kbd>, <var>, <samp>, <tt>, <br>, <hr>,
<a>, a <href>, <p>, <ul>, <ol>, <li>, <menu>,
<dl>, <dt>, <dd>, <base href>
In particular, do not use style sheets, tables or background colors or images.
|The same message can be sent in the same message in both plain text and HTML format.
The receiving mailer will only show the HTML version, if it supports HTML, otherwise
it will only show the plain text version.
||Netscape, Outlook Express and Eudora (version 4.0.1) all allow you to produce and
receive messages in this format. Be sure to get Eudora 4.0.1, since Eudora 4.0 does
not support this feature.
||Outlook Express sends in this format by default. Netscape and Eudora 4.0.1 allows
you to send in this format.
|Filled in forms can be sent either via e-mail or HTTP.
||Since some e-mail readers read their e-mail off-line, it may be better to use the
"mailto:" URL as the submission format for forms to be filled in by e-mail
recipients. A disadvantage with "mailto:" is however that it will often
not work for computer shared between several people, or where the user has not correctly
initialized his browser with his e-mail address.
||Start forms with the HTML construct:
FORM ACTION= "mailto:some-suitable-email@address"
|The full ISO 8859-1 character set can be used in messages, and also other character
sets if you specify them.
||Unusal (8-bit) character may not be handled correctly in HTML messages with some
||It is better to use the HTML encodings of unusual characters. For example, use "Ö"
instead of "Ö" for the German character "O with two dots".
