...at least in the minds of some mail admins. The real issue is that
there aren't any pervasive controls over who can send email for a
specific domain. As a result some legitimately desperate mail admins
have resorted to the big hammer.

Another more costly option is to use a service that will act as a mail
relay for you (e.g. dyndns.org's MailHop service), rather than relying
on your ISP.
Everyone is right, though... in general, just setting your smarthost
to smtp.comcast.net is enough to handle most of the issues.
