Hello Community 
I have a problem with mail request in my customer project.
Is about attachment. When .png or .jpeg is attached as a file to email, everything is correct. I can see picture, and open it.
But when same picture is paste inside text/comment then it going to be broken. And then I cant see it.

Do You have any idea how to resolve that problem? I have set max attachment size to 15MB and for sure attachment is not reach limit. I can see reason:
"Failed to add the following attachment to this issue because the file name is invalid", but have no idea how to resolve that.
Regards
