I've noticed that when you run
"attach" with -attachformat 0, you get a x-unix-mode MIME parameter.
My question is: why?

Jon did it that way originally, I don't know why.  I needed
a different format, with a Content-Disposition.  When I created
that, I dropped the x-unix-mode.

I'm embarassed to say that I don't remember why I did that.  I think that
it was because I looked at attachment headerss in emails that I received,
maybe even some created by mhbuild, and they had it.

Looks like an AppleMail thing, at least based on some simple searching
on the Net.

IMO, it is useless, and a security problem if MUAs honor the parameter
when saving an attachment.
