The commands listed below are some that we use often, but many more exist. Check the man page and documentation for more details and information.
newaliases. The purpose of the newaliases program utility of Sendmail is to rebuild and update the random access database for the mail aliases file /etc/mail/aliases. It must be run each time you change the contents of this file in order for the changes to take effect. To update the aliases file with the newaliases utility, use the following command:
[root@deep] /# /usr/bin/newaliases
|
makemap. The purpose of the makemap program utility is to create the database maps in Sendmail. The makemap command must be used only when you need to create a new database for file like aliases, access, or domaintable, mailertable, and virtusertable. To run makemap to create a new database for access, use the following command:
[root@deep] /# makemap hash /etc/mail/access.db < /etc/mail/access
|
Where <hash> is the database format, makemap can handles up to three different database formats; they may be hash, btree or dbm.
The /etc/mail/access.db is the location and the name of the new database that will be created.
The /etc/mail/access is the location of the file from where makemap will read from the standard input file.
