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.
-o: Use the suffix when creating messages.
-x suffix: Use this suffix.
-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, a lock file("<user>.lock"), flock() or lockf(), and open(O_EXLOCK) 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.
