 I'm a newbie to vm, and so far I like it very much, especially its
ability to extract messages from digests (I converted from elm).
However, I have one problem: sometimes vm does not recognaize my mail
packets. It knows the location of the file and everything but
sometimes it incorporates the mail and other times it tells me that no
mail has arraived, although mail did arrave.

 I think that depending on the first message of the packet, sometimes
vm does not recognize that the file is a valid mail file; for example,
editing the mail packet and removing the first message somtimes solves
the problem. 

 I inspected vm.el and there is a function called
vm-compatible-folder-p, but I couldn't make any sense of it (I don't
know elisp well enough).

 So the question is: what is it that vm is looking for in the mail
packet to recognize it? I can then write a small shell script that would add
that to the packet so that vm would identify it.

 BTW, I'm using vm 5.31 (beta), and  elm had no problem with any of my
packets whatsoever. Any help would be greatly appreciated.
