Understanding iCOD Requirements
E-Mail Requirements
Chapter 2 27
• In some environments, configuring your iCOD 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 2-1 Example Edit to Sendmail Configuration (/etc/mail/sendmail.cf)
DMmy_company.com
DSmailhub.my_company.com
This example assumes the following:
• the iCOD 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 iCOD 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 iCOD system is not advertised to the internet but hostname
mycompany.com is advertised and reachable from the internet
• e-mail is forwarded from the iCOD 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 iCOD e-mail messages are in the adm mailbox.
