December 11, 1993 MAIL.LOCAL 8

### NAME

mail.local - store mail in a mailbox

### SYNOPSIS

mail.local [-l] [-f from] user ...

### DESCRIPTION

mail.local reads the standard input up to an end-of-file and appends it to each user's ```mail` file. The user must be a valid user name.

The options are as follows:

-f from
  Specify the sender's name.

-l
  Request that username.lock files be used for locking.

Individual mail messages in the mailbox are delimited by an empty line followed by a line beginning with the string ``From ''. A line containing the string ``From '', the sender's name and a time stamp is prepended to each delivered mail message. A blank line is appended to each message. A greater-than character (``>'') is prepended to any line in the message which could be mistaken for a ``From '' delimiter line.

If the [-l] flag is specified mailbox locking is done with username.lock files. Otherwise, the mailbox is exclusively locked with flock(2) while mail is appended.

If the ``biff'' service is returned by getservbyname(3), the biff server is notified of delivered mail.

The mail.local utility exits 0 on success, and >0 if an error occurs.

### ENVIRONMENT

```TZ`
  Used to set the appropriate time zone on the timestamp.

### FILES

```/tmp/local.XXXXXX`
  temporary files
```/var/mail/user`
  user's mailbox directory
