Email sent using mailcore2 IOS contains multiple content-depositions

[fans3210]

As shown below. I sent an email with only one normal attachment, but as I checked the source of the email, I found there are two extra multi parts with content-deposition of 'inline'. Which confuses my friend's email app which was written using javamail. He always thought I sent him an email with inline attachments while I wasn't.

Is this a normal behavior? How to avoid sending such extra things?

I had the same problem and was looking for an answer

I tried to fix this problem by modifying the code in the "mailcore2/src/core/rfc822/MCMessageBuilder.cpp " file, as shown below. I changed "disposition" to "NULL" .
