The Mail Manager interface displays the fully qualified host name being managed in the ``Host Name'' entry. The default host name displayed is the name determined by sendmail. In general it will not need to be modified, but you may do so if necessary. For example, if your machine has multiple network interfaces, and sendmail chooses the wrong name, then you may want to redefine this value. The MM automatically updates the j, m, and w macros in the sendmail.cf file with the correct values. For more details on sendmail.cf macros, see UNRESOLVED XREF-0.
A ``fully qualified domain name'' (also sometimes called a ``fully qualified host name'') includes both the machine name and the domain name of a host. For example, consider a fully qualified host name mymachine.dev.footle.com where mymachine is the name of your machine, and dev.footle.com describes the domain. The dot is the domain separator. For more information, see ``DNS domain names and host names''.
To modify the host name:
A pop-up screen prompts for a host name, with a data entry field and a Select button.
The ``Select Host'' screen gives you the choice of sorting the scrollable index of host names by name or by IP address and a filename filter. There is a help message associated with the position of the mouse.
