I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

That has nothing to do with MFT and everything to do with Dan Bernstein
not being interested in you sending him copies of mailing list mail.
That is, incidentally, something that you do on all the mailing lists that
you're on, and it's incredibly obnoxious. I haven't gotten to the point
of bouncing your mail back to you yet, but I wish you'd quit it too.
