Newmail is a program to allow monitoring of mailboxes in an intelligent
fashion. It is based loosely on
biff(1) and the version of
newmail that was distributed with
Elm 1.7.
The basic operation is that the program will check the list of specified
mailboxes each
interval seconds and will list any new mail that has
arrived in any of the mailboxes, indicating the sender name, and the subject
of the message.
Each entry displayed can be in a number of different formats depending on the
mode of the program, the number of folders being monitored, and the status of
the message. If you're running it as a
window (e.g. ``-w'' or invoked
as
wnewmail) then the output will be similar to:
sender name - subject of message
Priority: sender name - subject of message
where <sender name> is either the name of the person sending it, if
available (the ARPA 'From:' line) or some other brief indication of origin. If
you are the sender, <sender name> will be replaced by "to
<recipient name>". If there is no subject, the message "<no
subject>" will appear on the screen.
Folders are indicated by having the folder name appear first on the output line,
as in:
folder: sender name - subject of message
If you're running
newmail without the windows option, then the output is
more suitable for popping up on an otherwise active screen, and will be
formatted:
>> New mail from sender name - subject of message
>> Priority mail from sender name - subject of message
Again, with folder names indicated as a prefix.
The flags available are:
- -d
- This will turn on the debugging, verbose output mode. It is not
recommended that you use this option unless you're interested in actually
debugging the program.
- -i interval
- This will change the frequency that the program checks the folders to the
interval specified, in seconds. The default interval for the program is 60
seconds. Note: if you change the interval to less than 10
seconds, the program will warn you that it isn't
recommended.
- -w
- Use of the ``-w'' flag will simulate having the program run from within a
window (e.g. the more succinct output format, and so on). Most likely,
rather than using this option you should be simply invoking
wnewmail instead.
File specs are made up of two components, the
folder name and the
prefix string, the latter of which can always be omitted. The format is
foldername=prefixstring, and you can specify folders by full name, by
simply the name of the user whose mailbox should be monitored, or by the
standard
Elm metacharacters to specify your folder directory (e.g.
``+'', ``='', or ``%'').
Folders that cannot be opened due to permission mismatches will cause the
program to immediately abort. On the other hand, files that do not exist will
continue to be checked every
interval seconds, so some care should be
exercised when invoking the program.
The program will run until you log out or explicitly kill it, and can internally
reset itself if any of the folders shrink in size and then grow again.
The default folder to monitor is always your incoming mailbox.
Some example invocations:
$ newmail
will check your incoming mailbox every 60 seconds.
$ newmail -i 15 joe root
will monitor the incoming mailboxes for ``joe'' and ``root'', checking every 15
seconds for new mail.
$ newmail "mary=Mary" +postmaster=POBOX
will monitor the incoming mailbox for user ``mary'', prefixing all messages with
the string ``Mary'', and the folder in the users
maildir directory
called ``postmaster'', prefixing all of those messages with ``POBOX''.
You can also have more complex monitoring too, for example:
$ newmail -i 30 $LOGNAME=me ${LOGNAME}su=myroot /tmp/mbox
will check every 30 seconds for the users mailbox, a mailbox that is the users
login-name with ``su'' appended (e.g. ``joe'' would become ``joesu'') and the
file /tmp/mbox, prefixing new mail for each with ``me'', ``myroot'' and
``mbox'' respectively.
