# newaliases.sendmail(8)

rebuild the data base for the mail aliases file

## NAME

newaliases - rebuild the data base for the mail aliases file

## SYNOPSIS

**newaliases**

## DESCRIPTION

**Newaliases** rebuilds the random access data base for the mail aliases file /etc/mail/aliases.  It must be run each time this file is changed in order for the change to take effect.

**Newaliases** is identical to \`\`sendmail -bi''.

The **newaliases** utility exits 0 on success, and \>0 if an error occurs.

Notice: do **not** use **makemap** to create the aliases data base, because **newaliases** puts a special token into the data base that is required by **sendmail.**

## FILES

- /etc/mail/aliases

  The mail aliases file

## SEE ALSO

[aliases(5)](/aliases/5.md), [sendmail(8)](/sendmail/8.md)
