How to set boundary before parse

[houjincheng1992]

As the title said, a given content not contain boundary, and I want to set boundary first and then use parse. Is there any method to do this, thx.

It's not currently possible. VMime uses the "boundary" parameter of the "Content-Type" field if available (you can force its value before parsing though), or tries its best to guess the boundary if the parameter is not present.

What does the content look like? Could you post an excerpt, or full data if possible?
