Emacs 18.58 rmail uses the default mode by `umask' to write the file
~/.newmail when transferring mail from the spool file to the user's
RMAIL file.  It would seem that a better guess at how the user wants
her email file modes to be would be to look at the spool file or RMAIL
file modes.

The mode for the autosave of the *mail* buffer also appears to be just
from the umask - perhaps this mode could also be copied from the RMAIL
or spool file.  Same seems to hold for the file %backup%~.

A related possible problem: when emacs is adding to the RMAIL file,
the file RMAIL is readable to all:

jkp@laphroaig '~' 394: L RMAIL
-rw-------   1 jkp      other     1908372 Aug 11 23:26 RMAIL
jkp@laphroaig '~' 397: : > RMAIL 
jkp@laphroaig '~' 398: L .newmail 
-rw-r--r--   1 jkp      other        3336 Aug 12 00:18 .newmail
jkp@laphroaig '~' 399: rm .newmail 
rm: remove `.newmail'? y
jkp@laphroaig '~' 400: 
jkp@laphroaig '~' 400: 
jkp@laphroaig '~' 400: L RMAIL  (at this time emacs is in the process
                                 of writing to the RMAIL file)
-rw-r--r--   1 jkp      other     1670444 Aug 12  1992 RMAIL
