Special Considerations

Configuring E-Mail on Instant Capacity Systems

In some DNS environments, no changes to the default /etc/mail/sendmail.cf file may be needed to properly route e-mail from the Instant Capacity system to HP.

•In some environments, configuring your system to properly send e-mail from the system to HP can require as little as a two line edit (or none) to the /etc/mail/sendmail.cf file. Configuring mail, including sendmail and DNS configurations, is usually handled by the IT team in most organizations.

Example A-3 Example Edit to Sendmail Configuration (/etc/mail/sendmail.cf)

DMmy_company.com

DSmailhub.my_company.com

This example assumes the following:

•The Instant Capacity system’s hostname is: myICODsystem.my_site.my_company.com

•The From field of the e-mail is set to my_company.com rather than the exact hostname of the Instant Capacity system. This is because most organizations do not advertise the names of their internal servers to the internet; however, they do advertise a few (select) high level domain names to the internet.

•The Instant Capacity system is not advertised to the internet but hostname mycompany.com is advertised and reachable from the internet

•E-mail is forwarded from the system to a mail relay host called mailhub. The mail server called mailhub may either be directly connected to the internet and send the e-mail directly to HP, or it may forward the e-mail to another mail server on its way to HP.

NOTE	Any bounced Instant Capacity e-mail messages are sent to the adm
	mailbox.
