Deciding Whether to Install sendmail

You must install sendmail in order to do the following things:

If you do not install sendmail, only local and UUCP mail will work. HP-supported user agents (programs that send messages to sendmail) and delivery agents (programs that sendmail uses to route messages) are listed in the section “How sendmail Works”.

	NOTE: If you are running a pre-HP-UX 10.20 version of sendmail on your HP-UX system, you cannot use the same /etc/mail/sendmail.cf configuration file with the version of sendmail included with HP-UX 10.20 and later. See the section “Migrating the sendmail Configuration File” for information on how to migrate your pre-HP-UX 10.20 configuration file.
