2004 – We need an email aliases file copy on lincoln which will act as the plat agent and mail server for our other domains. So I made a script /etc/mail/newaliases.sh which will transfer the aliases file from franklin to lincoln first and then run the system newaliases command.

So for the future change of aliases file, please run /etc/mail/newaliases.sh or under /etc/mail run “./newaliases.sh” instead of ?newaliases? after you vi the file /etc/mail/aliases.
