MAIL.LOCAL(8) Maintenance Commands and Procedures MAIL.LOCAL(8)

NAME

mail.local - store mail in a mailbox

SYNOPSIS

/usr/lib/mail.local [-f sender] [-d] recipient

DESCRIPTION

mail.local reads the standard input up to an end-of-file and appends
it to each user's mail file (mailbox). This program is intended to be
used by sendmail(8) as a mail delivery agent for local mail. It is
not a user interface agent.


Messages are appended to the user's mail file in the /var/mail
directory. The user must be a valid user name.


Each delivered mail message in the mailbox is preceded by a "Unix
From line" with the following format:


From sender_address time_stamp


The sender_address is extracted from the SMTP envelope address (the
envelope address is specified with the -f option).


A trailing blank line is also added to the end of each message.


The mail files are locked with a .lock file while mail is appended.


The mail files are created with mode 660, owner is set to recipient,
and group is set to mail. If the ``biff'' service is returned by
getservbyname(3SOCKET), the biff server is notified of delivered
mail. This program also computes the Content-Length: header which
will be used by the mailbox reader to mark the message boundary.

OPTIONS

The following options are supported:

-f sender
Specifies the "envelope from address" of the message.
This flag is technically optional, but should be used.


-d
Specifies the recipient of the message. This flag is
also optional and is supported here for backward
compatibility. That is, mail.local recipient is the same
as mail.local -d recipient.


-l
Turn on LMTP mode.


-r from
Specify the sender's name (for backward compatibility).


-7
Do not advertise 8BITMIME support in LMTP mode.


-b
Return a permanent error instead of a temporary error if
a mailbox exceeds quota.

OPERANDS

The following operand is supported:

recipient
The recipient of the mail message.

ENVIRONMENT VARIABLES

EXIT STATUS

0
Successful operation.


>0
An error occurred.
