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

NAME         top

       newaliases — rebuild mail aliases

SYNOPSIS         top

       newaliases [-f file]

DESCRIPTION         top

       The newaliases 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, newaliases is equivalent to running
       makemap(8) as follows:

             # makemap -t aliases /etc/mail/aliases

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

             # 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
       occurs.

SEE ALSO         top

HISTORY         top

       The newaliases command first appeared in OpenBSD 4.6 as a
       replacement for the equivalent command shipped with sendmail.
