rebuild mail aliases


newaliases [-f file]


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/opensmtpd/aliases.

The options are as follows:

-f file

Use file as the configuration file, instead of the default /etc/opensmtpd/smtpd.conf.

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

# makemap -t aliases /etc/opensmtpd/aliases

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

# smtpctl update table aliases
