This is a Mime Mail component module (for use by other modules).
- It permits users to receive HTML email and can be used by other modules. The mail functionality accepts an HTML message body, mime-endcodes it and sends it.
- If the HTML has embedded graphics, these graphics are MIME-encoded and included as a message attachment.
- Adopts your site's style by automatically including your theme's stylesheet files in a themeable HTML message format
- If the recipient's preference is available and they prefer plaintext, the HTML will be converted to plain text and sent as-is. Otherwise, the email will be sent in themeable HTML with a plaintext alternative.
Mime Mail picks up your standard CSS and applies the CSS in a way that works in all email clients which accept HTML email. Mime Mail looks for print.css to override the standard formatting, usually to remove background colours and images that create problems when printing or viewing on handheld devices. Mime Mail also looks for a mail.css file to provide special formatting separate to the print version.
There are some issues open in the alpha version of Mime Mail for Drupal 6. If you use subthemes or multiple themes, you might end up with a different theme to what you expect.
