Encoding Inline Graphics

[bcooney]

Recently, our inline graphics have stopped appearing in client's with Apple Mail. These graphics are attached using EmailAttachFileInline ( data ; contentId ). They are .jpgs. and are stored with SuperContainer.

 

We have noticed a change in the content-type:

 

 

#1 

From a successful email:

 

------=_Part_555932_2165159.1335572538253

Content-Type: image/jpeg

Content-Transfer-Encoding: base64

Content-ID: <graphic1>

 

#2

 

From a failed email:

 

------=_Part_66067_1267341.1352937703276

Content-Type: application/octet-stream

Content-Transfer-Encoding: base64

Content-ID: <graphic1>

 

I do not see where I have the ability to control this setting. The customer's IT dept reports no recent changes to the mailserver. Please point me in the right direction and let me know if you need further info.

 

Many thanks,

Barbara
