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(1M) 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 get- servbyname(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
TZ Used to set the appropriate time zone on the timestamp. EXIT STATUS
The following exit values are returned: 0 Successful operation. >0 An error occurred. FILES
/tmp/local.XXXXXX temporary files /tmp/lochd.XXXXXX temporary files /var/mail/user_name user's mail file ATTRIBUTES
