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.
