Special Considerations
Configuring E-Mail on Instant Capacity Systems
Appendix A146
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.
