It will also remove all images which are within the message itself (but not attachments).</li><li><strong>Send the message as HTML only</strong>: If you select this option, keep in mind that some mail programs may have trouble displaying the message as no separate plain-text representation is sent.</li><li><strong>Send the message as both plain text and HTML</strong>: This option is the best trade-off between compatibility and retaining applied formatting and embedded images, but increases the message size.</li></ul><p>Settings for entire domains:</p><ul><li><strong>HTML and Plain Text Domains</strong>: These options explicitly set HTML or plain-text preference for all users in the given domains (i.e., the part of an e-mail address after the <q>@</q>). Use the Add button to add the domain names that you typically send mail to, if you know which domains can display HTML-formatted mail messages, and which domains can only display plain text.</li></ul><p>Settings depending on the message content:</p><ul><li><strong>Automatically send the message as plain text if no significant formatting is present</strong>: Use this option to convert messages which were composed in HTML to plain text to reduce the size of the message if no or non-significant formatting has been applied. <q>Significant</q> in this case includes bold or italic fonts, underlining, custom colors, etc. This test is performed <em>before</em> the address book or domain settings are consulted to determine the send format.</li></ul><p>For example, if you typically send mail to multiple recipients that have the same domain name (for example, your colleagues all have email addresses that end in <q>netscape.net</q>), and you know that this domain name is capable of displaying HTML messages, then you can add the netscape.net domain to the list of HTML Domains so that Mail & Newsgroups will automatically send messages in HTML format to these recipients (note that no plain-text part is sent in this case).</p><p>Similarly, if you typically send mail to recipients at a domain that you know can only receive Plain Text messages, you can add that domain name to the list of Plain Text domains, so that Mail & Newsgroups automatically sends messages to that domain in plain-text format (no HTML part is sent).</p><p>Whenever you add a person or address card to your address book, you can specify whether that addressee can receive HTML-formatted messages. However, when this information is unknown, you can set Send Format preferences for how Mail & Newsgroups formats these messages.</p><p>You can always override these preferences for an individual message by using the Options menu in the Mail Compose window.</p><p><strong>Note</strong>: If you regularly compose HTML (formatted) mail messages, keep in mind that sometimes not all recipients use mail programs that can display HTML formatting properly. Send Format preferences allow you to specify how you want to format messages that go to recipients who cannot display HTML-formatted mail. You can convert messages to plain text, format them only as HTML, or format them as both HTML and plain text.
