Subject [jira] Updated: (EMAIL-50) [email] HTML Emails with images don't display in Outlook 2000
Date Sat, 10 Feb 2007 01:52:05 GMT


Ben Speakmon updated EMAIL-50:

    Attachment: html-embed-images.patch

Attaching a cleaned-up and debugged version of the original HtmlEmail patch with new embed()
tests. Confirmed to work properly on Thunderbird, Gmail, and Mac Mail.  

EMAIL-28 was being caused by the same things that were causing Outlook to fail, so the important
point is that this was never an Outlook-specific problem but was a bug in how commons-email
was constructing complex HTML messages. This patch fixes EMAIL-28 as well as this patch.

The original patch also fixed EMAIL-52, and this one does the same.

> I was having a problem sending HTML Emails with inline image attachments against
> the client Microsoft Outlook 2000 SP-3.  I am using commons-email-1.0.jar.
> This bug report proposes a solution include code.
> Suppose with an HtmlEmail I am embedding 2 images, adding an HTML part and Text
> part.
> The resultant Body structure is:
> Entity	Content-Type		Encoding
> 1	text/plain		7bit
> 2	multipart/related
> 2.1	text/html		7bit
> 2.2	image/jpeg		base64
> 2.3	image/jpeg		base64
> Outlook, by default, shows the text part with the HTML email as an attachment
> (correctly showing the images).  My "problem" is that I think the HTML should be
> shown by default.
> I am guessing that it is an issue with this particular email client and the Body
> Structure format ?  (see here, for example: COM-1526)

> I have fixed this for my own purposes and am recording the details here for the
> benefit of others.  I don't know whether this should be categorised as a bug in
> commons-email-1.0.jar or a bug in Outlook.  I suspect the latter, but since back
> versions of Outlook will never get fixed, the pragmatic solution is to alter
> commons-email, particularly in cases if you are targeting a known finite set of
> email clients.
> I am fully expecting a committer to categorize this as WONTFIX, but at least the
> attachment I will add may allow others to use my code.
> My code has been tested to work on:
>   Microsoft Outlook Express 6.00
>   Microsoft Outlook 2000 SP-3
>   Microsoft Outlook 2002
>   Microsoft Outlook 2003 
>   Qualcomm Eudora
>   SquirrelMail 1.5.1 (webmail client)
>   Hotmail (as of November 2005)
>   Gmail (as of November 2005)
> These clients are all happy to receive and display HTML emails in the expected
> way using this Body Structure:
> Entity	Content-Type	Encoding
> 1		multipart/alternative 
> 1.1		text/plain		7bit
> 1.2		text/html 		7bit
> 2		image/jpeg		base64
> 3		image/jpeg		base64
> I have not tested with attachments that do not relate to the HTML and may not
> support this scenario; however this is not normal usage scenario (well, for me
> anyway).
