Mail aliases are sendmail's way of redirecting mail from some address on your system to another destination. That destination can be a user on your system, an email address on another system, a file or the input to a program. Aliases apply for all domains for which your system accepts email. Thus, if your system accepted mail for the domains `abc.com` and `xyz.com`, an alias for the address `foo` would redirect mail sent to both `foo@abc.com` and `foo@xyz.com`.

At the top of this page is a form for entering the details of a new mail alias. Beneath the form is a list of existing aliases and the destination(s) for redirected email. To edit an alias, click on its name.

If you are using the Majordomo module, you may notice several aliases like `Majordomo`, `owner-listname` or `listname-request`. Do not modify these aliases unless you know what you are doing.
