First of all, VM doesn't set line ending formats.  Emacs does.

Secondly, the variable file-coding-system-alist, according to its
documentation, sets the coding system for *reading* files, not writing them.
So, it is a bad idea to set line-ending format there (or even one single
coding system for all types of files).  From what you write later on, I
suspect that your imap-cache folders might have gotten corrupted as a
result.

How Gnu Emacs decides the line ending format for the files it creates is a
bit of a mystery.  All I have in my customizations is 

(if running-fsf
    ;; (setq-default buffer-file-coding-system 'iso-latin-1-unix)
    (setq default-buffer-file-coding-system 'utf-8-unix)
  )

This seems to tell Emacs that it should use unix line endings all the time.
I can't be sure.  But I have never had Emacs create new files with DOS line
endings.
