Description Don Pellegrino 2016-12-05 15:06:19 UTC

Description of problem:

Using mutt with the default mailcap, Firefox is used to view text/html attachments that are part of a multipart/related attachment. However, the image/jpeg attachements that are part of the same multipart/related attachment are not rendered. Instead they are shown as broken links.

Version-Release number of selected component (if applicable):

Summary : A text mode mail user agent
Description :
Mutt is a small but very powerful text-based MIME mail client. Mutt
is highly configurable, and is well suited to the mail power user with
advanced features like key bindings, keyboard macros, mail threading,
regular expression searches and a powerful pattern matching language
for selecting groups of messages.

How reproducible:

Always

Steps to Reproduce:

1. Use mutt to view an IMAP folder.
2. Open an IMAP message having a multipart/related attachment made of html and images.
3. Observe the Firefox opens and renders the html but displays broken links where the images should be rendered.

Expected results:

The HTML with images should be rendered.

Additional info:

Not sure if this should be a bug against mutt or mailcap.

Hi.

In fact firefox cannot display text/html attachment properly. In mails are used resource locators different to locators used in web [1] therefore firefox shows
it as a broken link.

The other problem is that when you view an text/html attachment in mutt,
only the text/html part is extracted and sent to firefox (or any other 
program). No other parts (eg. the images) are extracted from the mail message.
