在SwiftMailer生成的电子邮件中更改Multipart Boundary？

Question

Thanks for reading!

I want to change the default multipart boundary string in a message generated by SwiftMailer.

SwiftMailer seems to automatically generate the string, and includes the string "swift_v4...", like so:

--_=_swift_v4_135388916050b2b5889e516_=_

        ...Text Message Part...

--_=_swift_v4_135388916050b2b5889e516_=_

        ...HTML Message Part...

--_=_swift_v4_135388916050b2b5889e516_=_

I don't see anything in the documentation, but before I go digging around in the code, does anyone know a way to change this via the SwiftMailer interface?

Judging from the source code, this can be done simply via Swift_Message::setBoundary().
