Forward and reverse lookup match; sendmail will not complain about
the mapping (BTW: I'm the sendmail maintainer, so I know a bit about
MTAs and anti-spam measures... and as I run the next generation of
sendmail on my system I won't use some external "smart host".)

You need an in-addr.arpa delegation.  Then you can make the appropriate
entries in your DNS server.  Unfortunately, I rate the chances of
pacbell delegating a DSL user a reverse zone about zero.

Nowhere near that high ;-)
