local.users(4) Kernel Interfaces Manual local.users(4)NAME
local.users - Specifies mail recipients on the local host.
DESCRIPTION
The local.users file contains a list of user names whose mail is to be delivered to the local host and whose return address is user-
name@hostname. Entries in the local.hosts file are in addition to other local users (such as root and postmaster). See sendmail.cf(4) for
a description of other local users.
You can add entries to this file if the host is configured as a simple client and either of the following is true: The user wants their
mail delivered on this machine rather than being forwarded to the mail server. You are adding aliases to the /var/adm/sendmail/aliases
file. When the host is configured as a simple client, the alias must be added to this file and the aliases file.
A simple client is defined as a host that had the mail system configured using the MailConfig application from the System Management utili-
ties or configured using the mailsetup utility's Quick Setup menu.
The format of the file is as follows: User names are separated by blanks or new lines. Multiple user name can be specified on a line.
Blank lines are ignored. A comment mark (#) ends the line.
After modifying the local.users file, you must restart the sendmail daemon to apply the changes. Use the following command: #
/sbin/init.d/sendmail restart
EXAMPLES
root postmaster rw # A comment followed by an ignored blank line.
# Another comment. mariah # Another comment.
carey # Leading blanks are acceptable.
FILES

aliases(4) Kernel Interfaces Manual aliases(4)NAME
aliases - Contains alias definitions for the sendmail program
SYNOPSIS
/var/adm/sendmail/aliases
DESCRIPTION
By default, the aliases file contains the required aliases for the sendmail program. Do not delete these defaults because they are needed
by the system. This file describes user ID aliases used by the sendmail command. It is formatted as a series of lines in the form: name:
name_1, name_2, name_3,..
The name is the name that needs an alias, and the name_n are the aliases for that name. Lines beginning with white space are continuation
lines. Lines beginning with a # (number sign) are comments.
You can define an alias only on local names. Duplicate addresses are removed and no message is sent to any person more than once. For
example, if name_1 defines an alias that is name_2 and name_2 defines an alias that is name_1, sendmail does not send the same message back
and forth. Local and valid recipients who have a .forward file in their home directory have messages forwarded to the list of users
defined in that file.
This is only the raw data file; the actual information that defines the aliases is placed into a binary format in the files /var/adm/send-
mail/aliases.dir and /var/adm/sendmail/aliases.pag using the newaliases command. For the change to take effect, the newaliases command
must be executed each time the aliases file is changed.
The sendmail program also supports sending messages to programs or appending a message to a file. See the sendmail(8) reference page for
further information.
Special Aliases
Directs error messages that occur when sending to aliasname back to address.
RESTRICTIONS
Aliases for sendmail use the dbm(3) database format for faster lookups. A single alias cannot exceed 1,000 characters. To work around this
restriction, you can chain together aliases. For example: alias-list: ali1, ali2, ali3 ali1: name 1, name 2 ... ali2: name n, name n + 1
