man incm (Commandes) - Incorporating new mails for Mew

NAME

incm - Incorporating new mails for Mew

SYNOPSIS

incm [options]

DESCRIPTION

The incm utility incorporates new mails from the mbox or the maildir to Mew's inbox folder.

The options are as follows:

-a
Retrieve all mails from maildir/{cur,new} for maildir.
-b
Backup mails. mbox: No truncate mbox file. maildir: To maildir/cur directory.
-c
Use the Content-Length: field, instead of the "From " line, as a mail separator for mbox.
-d path
Path to mbox/maildir. If path is a file, mbox is assumed. If path is a directory, maildir is assumed.
-m path
The same as the -d option.
-s
Read one mail from stdin instead of mbox/maildir.
-i inboxdir
A path to the inbox directory.
-u
Don't touch ".mew-mtime".
-f
Preserve Unix From (Envelope Sender) line in mbox case.
-p mode
Specify file mode that creates in mbox case.
-h
Display this help message.
-v
Display the version.

mbox

For mbox, the mail separator is "From " in the beginning of lines. The incm utility does not convert ">From " to "From " in the beginning of lines in the body. On Solaris, Content-Length: should be used with the -c option to tell the end of mail.

To lock mbox, both a lock file("user.lock") and flock() (or lockf(), or open(LOCK_EX) are used.

maildir

For maildir, no lock and no separator are necessary.

Consider the following situation: 

        cur/{1,2}
        new/{3,4}

Executing incm without the options results in: 

        cur/{1,2}
        new/{}
        to inbox: {3,4}

Executing incm with the -a option results in: 

        cur/{}
        new/{}
        to inbox: {1,2,3,4}

Executing incm with the -b option results in: 

        cur/{1,2,3,4}
        new/{}
        to inbox: {3,4}

Executing incm with the -a option and the -b option results in: 

        cur/{1,2,3,4}
        new/{}
        to inbox: {1,2,3,4}
So, if both options are specified, messages are retrieved multiple times.
