newaliases - rebuild the data base for the mail aliases file
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.
