NEWALIASES(8)            System Manager's Manual           NEWALIASES(8)

NAME         top

       newaliases — rebuild mail aliases

SYNOPSIS         top

       newaliases [-f file]

DESCRIPTION         top

       The utility makes changes to the mail aliases file visible to
       smtpd(8).  It should be run every time the aliases(5) file is
       changed.  The location of the alias file is defined in
       smtpd.conf(5), and defaults to /etc/mail/aliases.

       The options are as follows:

       -f file
               Use file as the configuration file, instead of the
               default /etc/mail/smtpd.conf.

       If using database (db) files, is equivalent to running makemap(8)
       as follows:

             # makemap -t aliases /etc/mail/aliases

       If using plain text files, is equivalent to running smtpctl(8) as

             # smtpctl update table aliases

FILES         top

       /etc/mail/aliases     List of local user mail aliases.
       /etc/mail/virtual     List of virtual host aliases.

EXIT STATUS         top

       The newaliases utility exits 0 on success, and >0 if an error

       the equivalent command shipped with sendmail.
