newaliases rebuilds the random access data base for the mail aliases file /etc/mail/aliases.

newaliases accepts all the flags that sendmail(1M) accepts. However, most of these flags have no effect, except for the -C option and three of the Processing Options that can be set from a configuration file with the -o option:

-C /path/to/alt/config/file

Use alternate configuration file.

-oAfile

Specify possible alias files.

-oLn

Set the default log level to n. Defaults to 9.

-on

Validate the RHS of aliases when rebuilding the aliases(4) database.

newaliases runs in verbose mode (-v option) automatically.
