It's all really somewhat more subtle than this.  First off, the
15.20.88.126 address won't do anyone (outside of HP) any good since this
address is not reachable from outside of HP.  Second, "apollo.com" does
exist, and refers to an address (15.254.24.1) that IS reachable.  If
you have an incredibly (months and months) old copy of the Internet host
table, your entry for "apollo.com" says 129.248.0.1, which is its old
address and which doesn't work any more.  Third, "apollo.hp.com" has
MX records which lead you to some reachable hosts that will forward mail
to people at HP/Apollo.  If your sendmail that talks to the outside world
is old enough to not support MX records (say, like--oops--the Apollo
sendmail), then you won't be able to use "apollo.hp.com".  Otherwise,
"apollo.hp.com" should be the address you use.  The spaces of user names
under "apollo.com" and "apollo.hp.com" are identical (i.e.,
"foo@apollo.com" and "foo@apollo.hp.com" are equivalent).
