ZCO with Outlook sending invalid inline .jpg emails

Postby dan3857 » Wed May 17, 2017 3:27 am

I think I found another bug in ZCO, can someone confirm?

In Outlook with ZCO, click New Email, enter your email in the To: field, then click the Insert tab, then click Pictures, and insert any .jpg file into the body, then send the email.

This should create an email with the picture embedded in the email, but the MIME encoding of the jpg inline is blank. Outlook then shows a blank box where the image should be. Putting a .gif, or .png file works fine. It's just .jpg files.
Opening the email in Zimbra webmail works fine, and Thunderbird works fine. Those email clients can deal with malformatted MIME encoding.

The MIME encoding shows this:

Code: Select all

------=_NextPart_000_0105_01D2CE99.AECCA110
Content-Type: ;
        name="image001.jpg"
Content-Transfer-Encoding: base64
Content-ID: <image001.jpg@01D2CE99.AE6A83E0>


The Content-Type: field should say image/jpeg, but it's blank.

Outlook 2016 64bit with ZCO 8.7.1.1661, Zimbra NE 8.7.7
