Download Deploying DNS and Sendmail

The corp Subdomain
• Delegating Your First Domain
• Configuring the corp Domain
• POP/IMAP
Congratulations! You just suffered through the basics of configuring DNS and
Sendmail and emerged relatively unscathed.
In this section we'll complicate our initial example by creating a new subdomain
called corp.sysiphus.com and then delegating that domain to another server.
Delegating a domain means handing it off to another (administrative) group to
manage on their own. This is how DNS scales for large companies.
We'll also digress a bit in this section to talk about POP (Post Office Protocol) mail
and IMAP-- good systems for allowing PC users to read mail from a Unix server.
