I've noticed that rmail determines which mailbox to read by looking at
the LOGNAME environment variable. It prefers LOGNAME over USER, which
means if I log in (for example) as root, and then `su' as bob, and try
to read mail, I get an error to the effect that `bob' can't read
`root's mail. Here's the code where it figures out who you are for
the sake of reading mail:
(list "~/mbox"
(concat rmail-spool-directory
(or (getenv "LOGNAME")
(getenv "USER")
(user-login-name))))
Were I running things, I would check in the exact opposite order. My
question is: does anybody know the reasoning behind this code?

Yup. Here is a bit of code that causes it to happen automatically; I
believe I snarfed it from this mailing list several months ago.
; Reset mail-aliases to t when ~/.mailrc is written, so that mail-aliases
; will get updated before next send."
(setq write-file-hooks (cons 'alias-check write-file-hooks))
(defun alias-check() ""
(if (equal ".mailrc" (file-name-nondirectory buffer-file-name))
(setq mail-aliases t))
nil)

I long ago got bored with this game and make the following small hack to ensure that editing the .mailrc (using emacs, of course) caused the variable to be reset automagically, and hence brought the changes made into effect immediately. Insert the following lines at the bottom of your .mailrc: # # Local Variables: # eval: (setup-mailrc-hook) # End: And put the following two function definitions in your .emacs, or where-ever: (defun mailrc-reset () (message "Reset aliases variable") (sit-for 1) (setq mail-aliases t) nil) ; this is rather important! (defun setup-mailrc-hook () (make-local-variable 'write-file-hooks) ; make it have a separate value here (setq write-file-hooks (cons 'mailrc-reset write-file-hooks))) .
