[Ext] set custom attachment headers

Thunderbird
#1

hello :),

i am developing an extension for a very specific use case for thunderbird.
When attaching a special type of file to an email i want to set customHeaders for that attachment (not the email).

I tried many things, but can not find a way to do it.

Is it even possible?

bengtler,

We are no longer using discourse.

You’ll want to post this at https://thunderbird.topicbox.com/groups/addons
