[gnu.emacs.bug] mysterious behavior of rmail and multiple mail files and inboxes

kek@DINORAH.WUSTL.EDU (09/07/89)

running 18.51 emacs
ultrix 3.1

after extablishing  a second inbox in /usr/spool/mail/
and in RMAIL mode doing
i XMAIL RET
followed by
M-x set-rmail-inbox-list RET inbox_name RET
I find that the 
g RET 
does not merge new mail.

I tried saving the XMAIL file, exiting and returning to RMAIL, putting
the inbox in my home dir rather than /usr/spool/mail, all to no avail.

C-u g inbox_name RET
does bring new mail into the XMAIL buffer but does not remove the inbox.


Am I describing the unworthy behavior of 18.51 or did I miss something?
We have available 18.54 (I think that is the number) but haven't taken
the time to install.  Is this the reason for the time I need to take?

PS is there a clue to this in the help apropos for inbox  ?
set-rmail-inbox-list	      
  Function: Set the inbox list of the current RMAIL file to FILE-NAME.  This may be[sic]
