When getting new mail, Rmail first copies the new mail from the inbox
file to the Rmail file; then it saves the Rmail file; then it truncates
the inbox file. This way, a system crash may cause duplication of mail
between the inbox and the Rmail file, but cannot lose mail. If
rmail-preserve-inbox is non-
nil, then Rmail will copy new
mail from the inbox file to the Rmail file without truncating the inbox
file. You may wish to set this, for example, on a portable computer you
use to check your mail via POP while traveling, so that your mail will
remain on the server and you can save it later on your workstation.
In some cases, Rmail copies the new mail from the inbox file
indirectly. First it runs the
movemail program to move the mail
from the inbox to an intermediate file called
`~/.newmail-inboxname'. Then Rmail merges the new mail from
that file, saves the Rmail file, and only then deletes the intermediate
file. If there is a crash at the wrong time, this file continues to
exist, and Rmail will use it again the next time it gets new mail from
If Rmail is unable to convert the data in `~/.newmail-inboxname' into Babyl format, it renames the file to `~/RMAILOSE.n' (n is an integer chosen to make the name unique) so that Rmail will not have trouble with the data again. You should look at the file, find whatever message confuses Rmail (probably one that includes the control-underscore character, octal code 037), and delete it. Then you can use 1 g to get new mail from the corrected file.
Some sites use a method called POP for accessing users' inbox data
instead of storing the data in inbox files.
movemail can work
with POP if you compile it with the macro
movemail only works with POP3, not with older versions of POP.
Assuming you have compiled and installed
appropriately, you can specify a POP inbox with a "file name" of the
movemail handles such a name by
opening a connection to the POP server. The
variable specifies the machine to look for the server on.
Accessing mail via POP may require a password. If the variable
rmail-pop-password is non-
nil, it specifies the password
to use for POP. Alternatively, if
nil, then Rmail asks you for the password to use.
If you need to pass additional command-line flags to
set the variable
rmail-movemail-flags a list of the flags you
wish to use. Do not use this variable to pass the `-p' flag to
preserve your inbox contents; use
movemail program installed at your site may support
Kerberos and/or GSS-API authentication. If only Kerberos or GSS-API is
supported, it is used by default whenever you attempt to retrieve
POP mail when
rmail-pop-password-required are unset. If both are supported,
then Kerberos is used by default; to use GSS-API instead, set
rmail-movemail-flags to pass the flag `-g' to
